Yonex Ai 98: tell me more about her

Syngut is a great string for demos. It's right in the middle.
Poly will take away some power, but add more spin.

right...

i felt pretty comfortable right off of the bat with this stick. for whatever reason, the trajectory of the ball coming off the strings was right on point.

i also demoed the APD+ last week (along with Pure Strike Tour, Control Tour, IG PP) and absolutely loved it. it seemed like I actually had more control because of the amount of spin I could generate. the ai98 does seem to have a bit more "feel" or directional control...I'm hoping that a poly at mid to low 50s can keep the power level but increase topspin and slice.

I've now put my tour g 310s on standby and using my ai98 as main stick. Its simply an all round more reliable racquet and i win more games when using it.. alas I only have one which will have to be rectified soon!

Dan, can you elaborate a little on your comparison between these two? I have on ai98, been enjoying it, but have been considering giving the 310g a good demo before committing to a second ai98. Thanks.

In a nutshell I find the AI98 is a lot more forgiving and gives me more margin for error. The 310 is very nice and when I'm playing my absolute best its yeilds great resulsts but at my level I really struggle with it when I'm against someone who hits really big groundstrokes.
The AI98 seemingly lets me turn around those situations turning defence into offence alot easier.
You may be a far better player than me and have the technique to handle it better - what is it that you're liking about the AI98 to make you want to demo the 310?

Thanks much for the input. I'm a 4.0/4.5 singles and doubles player and there isn't too much about the ai98 that I don't like. However, sometimes it feels like my groundstrokes get away from me a bit, i.e. a fair amount of power in the racquet that seems to need to be controlled. At the same time, and somewhat ironically, can't always seem to muster the pop on the serves that I've had with other racquets. For both these areas, could just be user error that some tweaking with strings and tension, and probably technique, can solve. But I've read that the 310 (and 330) is a pretty good serving stick, very stable at the net, and has good controllable power with that slightly denser stringbed. I like maneuverable racquets in the mid to upper 11-oz range, thus the interest in the 310 vs 330. So, mostly just an interest thing to see if the 310 might address some of my mostly minor complaints.

^ What are you stringing with and at what tension?

Previous string jobs were gut/co-poly, usually Pacific classic mains at 56, and a co-poly (MSV Co-Focus or WC Silverstring) at 52 in crosses. Currently, have a syngut main (ran out of gut) and co-poly cross at same tensions.

From my experience I've found the 310 to be far less stable at the net (and generally less manoeuvrable). Serving is different though and the one area where I prefer it over the AI98.
I string my 310s with a poly / synthetic hybrids and the ai98 with full poly pro tour @ 57lbs.

the more I play with AI98, the more I love it. I find that I get a few free points every match from this stick. Maybe it is a framed mishit that turns into a winner or maybe it is a perfectly executed shot, but i just get a few freebies with this racquet.

At stock weight, the only shot I find unpredictable is when going for a drop shot. I tend to leave them short of the net way too often..... or I float it too high and leave a sitter for my opponent. I think this has to do with the low swingweight.

Sorry, but I don't see how swingweight has anything to do with drop shot accuracy? Could be the flex of the racquet or your string setup. Drop shots just take practice when switching to a new racquet. You'll dial it in soon enough. Get a few buckets and use them as targets. With enough repetition, you will get it. People don't practice drop shots enough, but they result in deadly winners when executed properly.

Jack,

I probably wasn't specific. the swingweight is lower than my previous racquets, and that's why I'm not dialed in on the droppers. all other shots with the AI98 have required no changes to my game.

I could not get dialed in at all with this racquet...simply missing sw i think plus balance is not what I need so I either overshot or over spin this frame...
As a comparison for my game vcore 97 330 gram version felt like an extension of my arm...

Interesting, given that the stock 310 is 2 points more HL and 5 points less in SW than the stock AI98 (according to TW specs). I've got a demo of the 310 coming, so will give it a whirl and see how they compare.

I was demoing the ai98 vs the ezone xi98.
I was shocked at how differently they played for me.
The xi98 was a spin monster aeropro drive type frame and the ai98
was a flat ball low power frame for me.
I really wanted to like the ai98 but ended up getting the xi. With fresh strings I played like
Nadal with it although after crushing the ball with 18g strings the next day they mustve dropped a ton of tension and I couldnt keep a ball in court. I had another good outing though so ive decided to make the xi my new racquet and test string that hold up better.
I was using mosquito bite in both frames. Might try 18g razor code or rpm instead next.

I could see the ai98 being lethal with gut mains in an all court players hands but I prefer to baseline bash and need tons of spin.

lots of people seem to like it at first....but very few stay with it for the long haul.

That probably goes for a lot of sticks though - maybe even better - as there are lots of sticks that people don't even like initially. :p

I've just switched to this stick (lightly modded) after a month-long demo. I was playing with the TourG 330g for a while, but I've just found that I play better tennis with this racquet. I loved the TourG (that feel!), but outside of the sweetspot the ball just dies, and I was giving away too many free/easy points. Rallying with it is a dream, but in a match running from side to side, I'm just not consistent enough with it, and a couple points here or there can make the difference in a match. This stick is just more forgiving, and I haven't had trouble controlling the power or generating spin as some people here have. I can generate a heavy rally ball at 70%, and have easy power on tap when I finally get the short ball.

I just find I play better tennis when I don't have to play perfect tennis.

That's probably because the wrong sort of people buy in the first place. This isn't a stick suited to those with slow or short choppy swings.

Will be interested in hearing your comparison with the GRP. Used to play with the previous version of the Rad, though I understand the GRP is a bit different; TW sure seems to like it. I have Tour G 310 on the way and curious how that will play vs the Ai98. Lots of choices; a good problem to have I suppose.

because this stick needs longer time to adjust to, it is quite different really especially if you are coming from a control racket .. but once you dial it in there is no going back.

Can anyone compare this to the Prince Classic Graphite 100? The specs seem similar. I haven't played with either, but am curious if anyone has tried them both and has any thoughts. Thanks!

ai98 - more power, less spin, more of a flat serving racquet, feel is good, but not as buttery and soft as the prince. Easier to use, more modern for deep defensive shots.

Prince - less power, much more classic, more spin, better for kick serves, more open pattern, excellent for clay tennis. One of the best feeling sticks out there if you like to hit hard.

PCG100
- comfortable and plush
- fairly solid feeling
- big hoop, big sweetspot
- more of an old school feel
- easy to play with

Ai98
- more modern feel
- not quite as comfortable as the PCG100
- much more precise feeling and more control
- whippier and faster head speed
- encourages aggressive, heavy hitting

PCG100 is more like a Honda Accord, whereas the Ai98 is more like a Type-R. They both go down the road but the Type-R will be a lot quicker if you've got the ability to get the best out of it.

Jack, didn't you play with, or at least demo, the GRP for a while? Any comments on comparisons between that and the Ai98? Maneuverability, comfort, feel, etc.? Thanks.

I didn't play with the GRP long enough to offer any useful comments.
I played with the GR Mp though for a good bit.

Thanks, guys. I've played with a Prince Mono since it first came out, then switched to POG OS for a little while before going back to the Mono. Figured it was time for something new and couldn't decide if I should go for something more modern. I guess I'll demo them both and decide.

The main thing about the ai98 is the feel is modern. You will have to determine if you like that or not. I liked it a lot, but I still prefer a more classic feel. So to me, racquets like the POGs, Tec 315s, Head Prestiges, Yonex Tour Gs..etc are much better to me long term even though they are a little tougher to use.

I recently acquired an AI 98 and love it. It is a racket that is effortless to swing, powerful and has nice stability. Just wondering if anyone has switched to the AI 98 from the Pure Strike Tour, or the other way around. I currently use the Pure Strike Tour, but the Ai 98 gets the results and seems to be easier to use.
I'm a baseliner who hits heavy topspin. I also like to hit with pace. The Pure Strike Tour did that well for me. The Yonex, however, has a plusher feel that I like.

Managed to read the entire thread, hehe)) See quite a lot of mentions about Ai 98 being in same class as Blade 98, but didn't see detailed side by side comparison of these two. I assume "same class" means only that both racquets are equally demanding in terms of technique and physical abilities and that they provide similarly great feedback if their demands met? That doesn't mean they play the same though... Note that I'm interested about comparison to 18x20 version of Blade 98 only!

I'm average 4.0-4.5 (from 5.0 for groundstrokes and tactics and 3.0 for serve/volleys, hehe). Tall and skinny (never lifted weights), but capable of hitting some pretty heavy shots on both sides when my timing is OK and when opponent hits hard enough - heavily rely on using opponent's power to my advantage and have difficulties with putting away "sitters". Hitting mostly flat and hard, but enjoy injecting some heavy spin on angles and slice and generally mix up my shots, but always going perilously close to lines. Rarely ever step back from baseline, so hitting on the rise quite often, therefore need a fast and very stable racquet to keep balls in.

Currently using stock BLX Blade 98 as my main racquet (switch between full bed of various poly @25-26 kg and multi @28kg). Enjoy the plowthrough and stability of Blade, as well as pinpoint accuracy when hitting ball right, but find it too sluggish and tiresome for a long match due to high swingweight, especially on serve. Access to spin is generally low as well due to tight string pattern and low maneuverability, therefore often overhitting for 5-15 cm when cannot apply proper spin (which comes by default with such sticks as Prince O3 White or Yonex VCore 100S). The same goes for volleys - just find Blade too demanding on these for the same reasons, though know that it's rather me than racquet.

Looking at Ai 98 as a more versatile and heftier, but more maneuverable alternative to my Blade. Wonder if anybody can compare Blade 98 and Ai 98 in following compartments:
a) Higher Ai 98 static weight vs. higher Blade 98 swingweight:
- does the weight of two feel comparable on swing? I assume Ai 98 should swing easier
- does swinging Ai 98 feels less tiring than Blade 98 because of aerodynamics and weight distribution? I guess this requires comparison at end of long match. What I mean is that I feel much more tired after a match with Blade 98 than after similar match with easier swinging, but equally weighting Prince O3 White
- does Ai 98 feels as hefty on impact as Blade 98? from my experience Blade almost doesn't require applying any muscle power to generate heavy shot as long as you manage to bring it into hitting point in time, not the case with some heavier but more HL racquets
b) Access to spin - can apply some heavy top-spin with Blade as well, but require to spend more muscle power than with most other sticks, including 18x20-patterned (e.g. older Blades - those were easier to swing so were easier to spin with, but were less stable than BLX)

Also, could anybody compare flexibility of Ai 98 vs. Head (Flexpoint, Microgel, Youtek) Radical MP - does Ai 98 require as much "muscling" the ball as Radicals? Find latter too "deadened" in comparison to Blades, afraid to meet the same in Ai 98.

Just wanted to mention that I have no chance on demoing these, so will need to rely on your feedback.

Thanks in advance! Appreciate detailed answer!

Thanks for your reply! I guess I need opinions from less advanced players than Andy is... He's much stronger and skilled than me and can easily apply spin using his strength and fast swing whereas I need to do some wrist flicks, make more use of my western grip and "brush" the ball by changing position of racquet face rather than change the swing and "whip" the ball. In terms of physical strength I'm closer to Jason I think, but I'm swinging much faster and hit a flatter ball, so James also won't be a best reviewer for me either, I'm afraid... In terms of style of play and technique I'm closer to Sean, but he didn't review Ai 98 :(

The 98 is FAR easier on the body than the 100.. No idea where TW dream up these stats but serve 20 balls with both racquets and you'll see what I mean.

For me the 98 was a perfect balance between the 100 and the vcore g 310 - still easy on the arm like the vcore but a lot more forgiving and manourverable. I found the 100 to be too powerful and a little stiff whereas the 98 feels like it has the right aspects of a modern frame and a players frame if that makes sense.

I just bought a second one.

Very, very good racket. As the others have said it's a very good "all round" sort of racket with no real weaknesses. If I had to nitpick, I'd say its slightly muted feeling - the Rdis 100 MP (similar sort of racquet but more head light) has more direct feedback but that is sort of nitpicking.

Definitely for the higher intermediate and above player as its suits full, long, fast swings.

Good thread.

The other thing I forgot to say is that it takes small weight changes very well, so its very easy to "tweak" it to suit your particular game. I swapped out the grip and replaced it with one a couple of grams heavier and also added 1.5g to the upper third of the hoop. Love it!

Thanks a lot! Andy seems to be switching because of the same Ai 98 features that I'm looking to - easier access to spin and greater maneuverability without loss of control and feel. Anyway, already ordered mine! Going to arrive in a week, so hope to give some comparison between Blade 98 (18x20) and Ai 98 from a 4.0-4.5 players perspective pretty soon ;-)

I find the Ai98 to blow the doors off the Blade (I'm biased though...never liked the Blade line). The Ai just feels so much more solid AND still more maneuverable. No brainer to me!

I guess that depends on what do you mean by "solid" :) I find Blades to be very solid for aggressive baseline game and on serves thanks to some additional weight in the hoop. By that I mean that you can hit a very heavy ball without using too much muscle power even with a higher string tension; it doesn't get pushed around when you play against heavy hitters and it allows some pinpoint accuracy on groundstrokes even if you don't always hit by a center of strings' surface. But I agree they are not as versatile for intermediate-level player - it's possible to apply some heavy spin on groundstrokes, but it demands a lot from physical perspective and technique; it's also very demanding on volleys for me. But all in all, it performs as good as your effort is. The better effort, the better performance - it doesn't really have many flaws excepting for maneuverability. At least I think Blades are the most solid racquets of those weighting around 11.0 -11.4 oz.
