What have you been up to for 3 months ? Been fortunate to hit 7-9 times a week since April 1st. Took a free test for Covid -19 even though I had no symptoms. Negative Ghost Rider [emoji28]

@ByeByePoly where do you live ?

Still using velocity / cream ?
7-9 times a week ... you go girl. :-D :-D :-D Impressive.

I always take winter off since ending tennis club membership several years ago. I was ready to start hitting in spring and Covid hit. I would have started hitting by May, but got the bright idea to build my own privacy fence. Between battling the cemetery of buried past fence posts/cement and 3 weeks of rain, May disappeared. I have a thread in odds and ends on my fence project/war.

Good news is I have lost almost 10lbs on this misguided project ... if/when I return to tennis ... it will be at fighting weight.

Well, *there's* your problem right there ... you gotta use the 17ga, bruh <teehee>.

Seriously, I just have the one pack of the CX 17ga, and one pack of the plain AK in 16ga.

It'll be my first experience with this whenever I decide which stick to try it out in.

Received my 4 sets yesterday, strung one up and played. From the get go, I noticed this string was firmly comfortable, not mushy like a multi, and not bare bones like a synthetic. If felt really good. I strung it up at mid tension in my VC98, 52.5. I probably should have bumped it up to about 57. The string had good spin, adequate control, really nice power, and overall is a winner. I'll definitely spend more time with this string.

It strung up in my VC98 in an ATW in about 15 minutes. The string is a joy to string! I am impressed.

You think you'd prefer it in the mains or crosses in a poly hybrid? Guys in the other thread are raving about it as a cross with gut mains, which is what I usually play. That seems too good to be true, but I may just have to find out.

Hey Rabbit - any more thoughts on the AK Pro CX
Just did a playtest on a becker 11 18x20 with gut mains and Ak Pro at 50 Lbs (main &cross ) did not feel as good as Gosen Micro right off the stringer,
some what boardy feeling . Whats the break in time ,looks like a hard coating of some type for durability.
Thx

@BILL M - Hi, as promised, I restrung a VC 98 at 58 pounds and played today. I have not strung that tight in quite some time. :) The AK Pro CX performed quite differently; in a really good way. The sting bed was tight and uniform. The main two things I noticed were a) comfort is still there in spades and b) with increased tension comes lower launch angle. It'll take a little adjusting, and I'll probably settle in at 55 pounds but I was very impressed with its play and the results. This string is a winner, IMO and may take the place of my poor man's Champion's Choice. I've got two more sets and I'll string them up at 55 in my VC 98 Galaxy frames. Super nice string.

I strung some in a Wilson ProStaff 6.1 Stretch 95" 18x20. That beast weighs 12.8oz with syn grip and for some reason is not a joy to play with vs some of my other longbody rackets. I'll take it out for some serves in a couple of days after the rains pass. I have one more set I should string in a more "conventional" low powered racket. The only candidate right now is a noodly Chang Graphite OS I cut down to 27.25" I need to add a gob of lead to. Or maybe this mint Catapult 8 V-Engine 100 12oz 16x18 that if I didn't know better might have belonged to someone on this thread.

I've posted a few threads on AK Pro CX in the past year. Here's what I have used. I have used it in Yonex Vcore Pro 16x19 and currently in a Vcore Duel G 16x20 frame.

Full bed - plays really really nice. Firm yet comfortable. Low launch angle and the best snapback for a syn gut full bed I have used. The strings do not seem to get locked/stuck out of place like other syn guts as the AK Pro CX is not as gummy as more traditional syn guts.

AK Pro CX mains / Max Power crosses - Excellent Syn gut/poly hybrid that rivals the performance of gut/poly, especially for players with slower swing speeds or more old-school technique. Less power than Gut mains, a bit less spin, but more consistent and low launch angle... more forgiving overall but with a very similar overall feel to having natural gut mains.

Gut mains / AK Pro CX crosses - My current setup and possibly my holy grail string setup. Very comfortable, very linear and predictable - the launch angle never seems to surprise me, no matter how lazy I get. I strung this setup at 64/60lb and 25 hours later the gut mains are about 50% sawn through, but the setup is playing just as good as day 1. The tension maintenance is unbelievable, seriously. Still very tight, a very high pitch when hitting the strings.

do you remember what tensions you used on full bed ak pro cx? especially in the duel g 16x20? how is the durability if you used the ak pro cx 17?

60lb full bed when I used it in the duel G. It is a soft comfy string so even strung up tight it is not jarring at all.

I am still using this string in my Gut/ AK Pro CX hybrid and still loving it. At the moment I am using it in the Vcore Pro 16x19. I have the 17 gauge in at the moment and have no noticed no durability issues at all.

CX is a filament with high heat resistance, I guess in theory to reduce string wear and string breakage which happens due to the high temps generated by strings sliding against one another.

anyway tried this string strung at 63 lbs full bed and i got just 3 sets before it snapped at one of the main tie offs. Not sure if its something i did but usually don't have an issue with
thicker strings like syn gut or PPC 16 gauge. The string looks pretty thin to me in the 17g guage version, it took 1 g off of a 16g/18g multi syn hybrid. thinking if its a true 1.24mm then its 1.20mm strung.

any suggestions for stringing thin strings like 17 and 18? as far as knots and 1 piece vs 2 piece stringing?

Are you still using the AK Pro CX in your racquets? Any updates as to the tension(s) you have settled on? I am getting ready to try a set out. I am using it in the Yonex VC Pro HD 18X20 frame.

Picking up my Yonex tomorrow with Klip Legend and AK Pro CX! Pretty low tension, but my stringer recommended it to me to better match my RF97.

Do you know what tensions he put in that racquet?

I tried the RF97 A for a while. I liked playing with it a short while, maybe 15-20 minutes at a time. I bought one after demoing the club pro's version. Once I started using it full time I got some shoulder and wrist pain. Very odd because I had never had those issues with any other racquet I have ever used before. I tried several different strings, combos, tensions. I finally sold it. I hope you do not get any issues from it.

Played with the hybrid today 50# in both strings, and I'm honestly not very happy with it. It feels so stiff when I hit with it. The sweet spot feels absolutely tiny. My balls keep sailing into the net or long which I think is because the setup is forcing me to swing my racket a lot faster than I am used to to get more topspin. However, I think I am struggling with the swing weight.

That said... the temperatures also absolutely plunged over the past week so that might be more to blame. Went from ~80s to 40-60s. I'm not gonna call it quits yet, but I'm not feeling very optimistic about this setup.

If you check out the gut/ak pro CX thread I made, someone else tried the hybrid at lowish tensions as well and didn't like it very much. I think it is a setup that needs to be strung at 60lb or higher in the mains and crosses to get the best out of it.

Considering I have tried it at high tensions for three string jobs now, I might give it a go at 50ish pounds to see what I think.

been loving the tonic 16/ak pro cx 17 combo in my response ti at 62/60 much better then full bed cx which after a while moves around like crazy

50 seems pretty low for the rf97. bets its got a lot of power though

I tried a full bed at 60/60 and it locked up on me within 30 minutes of heavy hitting and the response turned boardy and jarring. I ended up cutting it out shortly after because my elbow started hurting. I have never tried it with gut before but it works very well as a main with a smooth poly cross string.

I was stringing it around 54 in my DR, but found because it was a brassier string it was really frame dependent. Loved it in my DR not as much in my Blade.

It's actually in a Yonex VCore 98+, not the RF97. Otherwise I would have strung at the higher end. My RF97 is normally strung at 58/52 w/ poly cross. It's warmer this weekend so I'll see how it does in warmer weather.

Played again today, and it was way better. So it might just be that my tensions are too high for when the temps are in the 40s. Today it was about 70-80s and was way more comfortable, hitting a good amount of top spin.

Same here. It is about at the end of the outdoor playing temps. It will be iffy from now until the end of the month. I hope I can get some outdoor hitting with this string before then. I can use my ball machine outside when it is nice.

Strings broke today. Honestly, I had a couple days of good tennis with the setup, but I think it's just not for me. I felt like the natural gut wasn't snapping back with the Gosen cross versus my Grapplesnake Irukandji.

I may give it a try as an alternative to natural gut in the mains with a poly in the cross though.

Hit with the Gosen + Tour Sniper combo yesterday in my RF97, and it hit phenomenally. Incredible control. Not as much top spin as my other setups though, but I think the RF97 is quite difficult for me to play with when I have to wear a mask indoors. I fatigue extremely quickly from being short of breath. Also extremely comfortable to hit with.

I may consider using Gosen instead of NG. I'll see how the durability is.

Keep us updated about the durability. I am trying to find another string besides NG as my main.

Play test now pending:

While we are sitting through a rare rainy day here in Los Angeles I just installed the 17 gauge/1.24 mm (natural color) in my Pure Strike VS (16x20/8-mains bridge) at DT36 == 25,5/23,2 kg.

That's my standard tension these days for firm multis such as Velocity/Multifeel/PPC so I'll be comparing apples-to-apples as far as tension goes.

I'll add some comments here when I get a few hours of court time with the GOSEN.

/Acey

[edit] don't look for durability data once I play some with AK CX. I hit quiet flat (learned on wood) and I am really easy on strings in general (counterpuncher all-court type game).

Any updates? Going to try CX probably in my next stringing (feels like mine will break in the next hour of play) and I use velocity at similar tensions as you (lately in hybrid with gamma ocho xp) so it would be great to have a benchmark before I show up to my stringer looking like this : :unsure:

Good to hear ... AK CX even more arm friendly than V. I have played a lot of hours with fb v 16 natural with zero arm twinge ... so my "safe" string. I will post if I try it. I have decided I would try AK CX/V @55/52 first ... that would be an exact comparison to O/V. I am surprised given the reported slickness of AK CX that the strings move around. That is a good attribute of O/V ... stays very straight in my tight 16/19.
Just strung a FB of AK Pro CX 17 (grey color version) to my PS97 V13 @55lbs. Hoping it won't feel as dead to me as Velocity and I will discover a new string. As you know from my other posts I love how V performs, just not how it feels. Will play tomorrow and report back. Did you ever end up giving it a go? If so, what were your impressions?

I warned you about hanging out in @mikeler 's thread. 8-B

Yes ... tried CX 16/V 16 ... always 16g for me.

I posted my comments here somewhere ... maybe this thread ... try search. I tried it because of @Znak ... so probably would have been a reply to him.

Short version based on memory:

- CX was less muted than V ... what isn't
- played great ... with a stiffer feel (more sg type of feel)
- felt slight elbow twinge after 2-4 hours which I did not expect, felt comfortable, so cut it out. I never violate that rule ... one twinge and I cut it out

I had great control with it ... definitely would have been a contender to fb V without the twinge.

fyi ... for me best feel and "enough" control was never going to be the same string. Always a tradeoff ... why I ended up with fb V ... checked off all the most important attributes for me. "Muted" wasn't a deal breaker ... and then kept V as the baseline to experiment with different mains trying to tweak in a little less "mute". I took all of 2020 off from tennis ... not sure when I will hit again, but if I ever got the string testing disease 8-B again gut/V would be in the list. I was always curious. I didn't love fb vs touch, or tonic/cream ... so not sure why I think gut/V might work. I did love the spin of tonic/cream ... noticeable difference ... friend on other side complaining. Funny thing is ... even then ... I would go grab the fb V racquet because I played better with it.

Thanks for taking the time to share again. I had not caught your feedback. I might have strung it a few pounds lighter had I read about your experience (I feel we are like-minded).
If you do ever feel like giving it a go, I would love to hear you opinion of ocho xp/Velocity. I stumbled on ocho by researching multis with the lowest possible stiffness rating. Saw the 8sided aspect and thought why not. It worked great for me and zero arm issues despite swinging for the fences.
