Sorry, I'm not going to give arbitrary tensions when I'm not familiar with Lynx, or your game etc. PTF will be most probably softer, and if you go to 17g, it's 1.20mm. Make your adjustments based on that.
would you suggest I do vs 17 g w/ fire at 55/53 so that I can compare with current vs / lynx tour 17g same tension? It’s a yonex 98 extended…

no worries ! Thanks much. I see you’re also a big fan of Tecnifibre Pro Red Code Wax 17 ? How would you compare vs Fire 17 G ?

PRCW is discontinued, so I switched to back PTF. I like both for different aspects. PRCW is stiffer and has less feel, but more predictable and consistent off the stringer, and was about 30% cheaper than PTF. PTF is softer and has more feel, but without the prestretch, the initial copoly softening is noticeable.

I wish they made PTF in black color. The red looks awesome on the VCORE frames but hideous on blacked out frames.
For those looking at a less expensive and more color friendly soft cross, Wilson Revolve Spin (the round one) does a pretty good job too in gut/poly.

where have you seen a blacked out frame with Fire on ? It looks okay on Kerber's blacked out racquet (the one she had a few months ago), with gut mains and stencil in black. Looks edgy ?

I'm using 55 VS gut 17 and 53 lynx tour 17
String the lynx tour crosses at a lower tension it will go a long way to improving feel and forgiveness. Kirschbaum Max Power is another string that will give you what you are looking for. I have found it slightly better than lynx tour as a cross string.

With these stiff polys that hold tension well it’s important to string them at a lower reference tension. I see a lot of guys on here think that they need to string at a magical differential of 2-3 lbs because their favorite pros do that or some other reason but the differential is an arbitrary number. Your differential will change based on the cross string being used, and if your playing a stiff poly that holds tension well it needs to be accounted for by lowering the reference tension.

Well I'm pretty sure if there was a black version, someone would complain it plays too differently from the red one. Personally if a string plays well, I don't care what color it is or how it (doesn't) match with the racquet/outfit etc.
As for Revolve Spin, I would not as it is shaped and thus will saw through the mains. If you are referring to the smooth Revolve, that loses tension fast and has very little feel. The slick coating also wears out very quickly.

I've tried both the PolyTour Fire and the smooth Revolve side by side and I felt I got more spin and comfort from Revolve. I use gut mains so feel isn't really an issue. Coatings on both strings wear off quite quickly if hitting with spin and on clay. Tension loss, both are comparable in my testing as well as on TW/USRSA. Both are great strings and very interchangeable as a soft decent durability cross for gut.

Well, I played tested all the coated strings on Playsight for a real comparison so I couldn't be biased or have a bad day etc. The mains are always Volkl Cyclone at 50lbs. My data shows the higher average spin was generated by PTF over Revolve 17. Revolve is softer, but lost more tension fast and played dead noticeably faster. PTF I noticeably feel the strings gripping and pocketing, during the good playability window. I suggest anyone interested should test both and discover for themselves.

Fair enough. I've added another PTF set in the shopping cart to try it again :)
I've never done such a scientific test on them but mostly going on how the 'balls looked'.
Did you test the same gauge, as the companies use different 'standards'?
PTF 17g is 1.20 but Revolve 17 is 1.25.
Just out of curiosity, what was the difference in average spin between the two?

They are the thinnest gauge available for each model. PTF had a 34rpm advantage but more importantly better feel and durability. Initially, without the prestretch, it had a pronounced playing curve, but 3-5% prestretch just tames the tension loss and allows the strings to perform at a linear curve. I do believe Yonex may have changed the formulation in the interim. I find the new stock to be softer than 3 years ago, and it does lose tension more than it did before. I have no proof of this. Maybe a RDC test of the stringbed stiffness of the 2 may verify this.

I was doing 62/60 with Lux Gut 1.30 / Max Power 1.25, which played great off the stringer but was lacking control after 4-6 hours.

I am now back to doing both mains and crosses at 62/62 (no differential) and the playability lasts a lot longer with a slight initial break in period, but I really like the consistency off the string-bed. I play with an eastern FH grip and like to play close to the baseline so high launch angle set-ups really frustrate me by 1. having to stand further back behind the baseline to control my shots, and 2. playing more defense than I would like...I am a type of player who prioritizes control over spin, but don't get me wrong I get more than enough spin with both mains and crosses at the same tension. I know most people here string their poly looser than the gut, but for those of you who like a low launch angle (or you just want your strings to last longer in general) try stringing with no differential.

So far no arm issues with either set-up, I know max power is on the stiffer side (my racket is quite heavy at 350 grams, and I use a flexible frame) but I will keep an eye on how my arm feels.

Won't be going back to Alu Power, thats for sure.

Yes you are probably better off stringing your gut/poly hybrid with no differential as the poly will lose more tension than the gut, increasing the launch angle over time.

62 for gut/poly for control is quite high. What frame do you use? Do you play in very hot conditions? Do you ping your frames when you string them or get them from your stringer to ensure you get close to what you asked to have pulled?

I use the head microgel radical MP, 18x20.

I play in fairly hot conditions, It's normally in the 90's here in Atlanta.

I don't ping my frames, I've been going to the same stringer for some years now so I mostly just go off how it plays.

I like higher tension than most on these forums, I was stringing very low for years based on what I read on these forums, now I am playing much better, more consistent.

Similar to you @aaron_h27, I like higher tensions than most here and string my Gravity Pro 18x20 @ 62/60 (VS NG/Ghostwire).

Have experimented a lot and really like this combo. I am still stunned by how durable it is: cost per hour almost identical to using a multi. I get around 8-9hrs from this setup whereas only get 3hrs from a multi or SG setup.

Racquet - Yonex Vcore Pro 330 (Green). String- Babolat or Luxilon natural gut mains 1.25 strung at 52 lbs. Alu Power Soft cross at 50 lbs. I go with the Soft as it holds tension a bit better than regular Alu. Setup remains playable for a long a time - 20+ hours of hitting.

Yes I am glad I figured it out. I was endlessly frustrated trying out different gut/poly set-ups. It plays consistently until it breaks!

I play with an eastern and also hate being backed up off the baseline. Had my first tennis elbow issue this spring, came back to vs/Alu power soft at 54/48. Really like it at first but now it’s launching a bit a month into it. I also wonder, wouldn’t poly mains/gut crosses provide a bit more control but still be soft on the arm ? Thinking of restringing a bit higher

With gut mains being so soft , I find that 90% the control comes from the cross tension. Try raising your cross tension until you feel you have adequate control.

My recent experience is lubricated gut/poly hybrid can last a very long time and still play rather well. However dead poly is still dead poly, just like in any other setup, it's bad for your arm.

I’m a big fan of the max power series. I also use VS Gut 16 mains around 56-57lbs in my rf97 with a 10% pre-stretch. I’ve been trying max power rough 1.25 and max power 1.25. The max power feels a bit crisper, cleaner, and holds tension a touch better. The rough has a bit more dwell time, a bit more spin, is a bit softer, and loses tension a bit faster. Overall I prefer the rough primarily for the better ball pocketing and slightly more spin.

I use poly tour fire 1.20 crosses with legend 1.30 mains. What do you lube up the strings with? I’ve tried synthetic oil and a silicone based lubricant. I like oil the best and PTF seems to hold it longer than other strings for some reason.

I lube when the strings start sticking which is after 6-8 hours of use for me. After I’ve lubed a couple of times I restring just the crosses to get back some control and get another couple of lube jobs out of it. Glad I’m not a string breaker.

I use mixture of beeswax and carnauba wax, and they work insanely well, if I apply every time before I play, string will never stick, it does reduce ball to string friction as well though. Used to play full bed gut and would break them close to 40 hour mark(both 16 and 17 no idea why there is not a difference), but with this, they last over 100 hours.

How do you apply the wax? I use a fine brush and just dab the string junctions, I try to not put too much on cos it gets on the balls and then your fingers. Does wax give you this problem? Do you rub it on like bow string wax?

I make a sort of emulsion with 99% rubbing alcohol and spring onto the string. It does get on the ball but only a little bit, looking at it after application you would think it's too dry but it works very well. If you like full bed natural gut but find them too expansive, this is the way to go. I do question it's value with gut/poly though.

I actually cut out only my crosses. I keep the gut mains intact, but restring the poly crosses. It’s a bit of a hassle due to the knots being on mains, but when they are out the mains are just a little lower, maybe 1-2 pounds. This helps me keep my gut mains for long periods of time, but I keep the stringbed fresh. I haven’t had any issues of warping.

Just sharing my experience with VS 17 and Lux gut 17 with Fire 17 - 55/53 - on my Ezone 98+ 2020 ; I tried, and I listed to @Sardines !! It’s just not the setup for me, it just doesn’t click. Compared to Lynx Tour 17 / VS 17 same tension, I got more power, more spin, better overheads.. more rpm on serves surely. But the predictability and control were just not there either because of the combination of strings on such a powerful racquet and/or because I just felt tight as I was getting afraid of getting balls sailing long. The launch angles were too high for someone who likes to hit mostly flat and likes to finish off points in 3/4 shots.. so yeah, back to the more reliable lynx tour 17 / vs17 at 55/52 to see if I get a little bit more power out of lynx tour, without sacrificing any of the control and predictability.

I suppose if you hit pretty flat then a slick cross isn’t really what you want. Some people like their stringbed better after it locks up.

Well personal taste is individual, so that's too bad. You asked for more power, spin, durability and comfort. You got all that, including a bigger serve, which would please most people. For most people with injuries, short of taking a hiatus, letting the racquet do some of the work of muscles is probably the only way to play while recovering. Normally, power comes at the cost of control, physics will dictate how much more power you can hit with with a perpendicular racquet face. But with a closed face and spin, a player can control a higher launch angle, and hit even harder. I'd suggest consider adjusting your game a little to accommodate a bigger serve. Launch angles can be tamed with tension changes or even a change of gauge. Maybe going to 1.25 or 1.30 will help?

Looking for a recommendation on a cross that plays similar to YPTP but with better tension maintenance? I’ve been stringing VS Touch 1.30 with YPTP 1.25 for one of my friends. He likes this setup, but is not happy with the tension maintenance. I had him try Max Power as a cross in the past but he did not like the stiff/crisp feel of MP. I was thinking maybe having him try Revolve or YPTF? Thoughts?

Both RS Lyon and YPTF would be the closest options.
 
If you wanted more control would you increase the main/cross differential or up the overall tension? Currently at 54/48 and after 5 weeks it’s a little unwieldy. Thinking of going 56/50 or should I just up the crosses?

Revolve is worse in tension loss. PTF is about the same but takes well to prestretching to deal with tension loss. Strike is a little stiffer but handles losses better.

Thanks for the replies. I pre-stretch gut, but have never pre-stretched a poly. How much pre-stretch are you doing on the Fire?

Also - has anyone tried Rev in a hybrid? It seems like a shaped version of Fire, is it not ideal in a hybrid due to the shaped profile of the string fraying the gut?

Exactly, Baseline is not a great poly for crossing with gut. It is like saying one doesn't like ice cream when they top it with mustard.
 
I've been playing with Hyper G soft main/Gosen micro sheep cross @ 51/53. Recently played with Hyper G soft full bed 49/47 but found it a tad lively after 5-6 hours so my ideal tension probably should be a bit higher like 51/49. My racket is Radical MP 2021.
I just ordered a set of gut ProV5 16 gauge from NGW which intend to used as a main hybrid. I'm guessing HGS will not be a good combo as it might cut through my main. I have sets of Ghostwire in 16L and 17, Pro Line evolution in 1.25mm and isospeed Cream in16L (I have old reels of tour bite, tornado and hyperion too but I doubt they'd be good crosses). Which one should I try first and at what tension? It will be my first time with gut (also a bit nervous to string it myself).
