You know I've strung and hit with GW since the Hyper G Soft playtest ended, and I've strung hundreds of frames with GW as a cross, Cream and Yonex Poly Tour Air as crosses. I"ve read comments from two posters recently who write that GW is softer than Cream and Swift. Two things tell me that isn't accurate: 1) lab data and 2) client breakage of those strings.
Here's my theory on your clients breaking Velocity Mains with GW Cross and Velocity Main and Cream sticking out of place:
GW is stiffer than Cream and is sawing into the 1.35mm Velocity mains as the Velocity slides back and forth across the GW crosses until Velocity snaps. Cream on the other hand isn't as stiff and it has a vast amount of elastomer which one can feel when stringing it. That elastomer (rubber) certainly doesn't make Cream or Swift (which is nearly identical to Cream in feel, play, and breakage) more slick than GW. Lab data might show Cream with a Cof of xxx, but when that rubber encounters another multifilament, Cream wears off the coating of the main string, Velocity and the mains begin to stick out of place.
When Velocity slides across Cream, the coating on Velocity wears off against the Cream crosses, and the Velocity sticks out of place just like a typical syn gut or multifilament.
To summarize: IMO GW is both stiffer and slicker than Cream and Swift. Having 4.0 and 4.5 clients who typically break main strings, not crosses, and who will play two identical setups with only one variable changed until they break a string gives a stringer more perspective than simply one player (myself) hitting with a setup. When other clients experience the same thing I experience, it makes my job easier as a stringer.
I've been down the road with GW / Cream in the mains with YPTA crosses and with NG main and GW and Cream crosses and string frames based on my theory that GW is stiffer than Cream / Swift. When Will Shelley, a 4.5C rated USTA player and the guy behind my Kobayashi Maur String Scenario thread breaks 1.28mm Cream mains 2X to 3X faster than 1.27mm Ghostwire, that's all the data I need. Will has been using GW 1.27mm Mains with YPTA 1.25m crosses since the spring of 2023 now, due to the much more frequent breakage of Triax 1.38mm / YPTA 1.25mm when he switched to the Ezone 100 frames. He was breaking Triax 1.38mm mains in roughly 8 hours and it became too expensive. But he broke Cream mains even faster than 1.38mm Triax. So I tried GW 1.27 mains which last him the longest of those three stings all using YPTA crosses.
The player breaks the Hyper G Mains of a Hyper G 1.30mm/1.25mm Head Hawk set up in his Ai 98 in 12 hours, he now has a serious elbow injury and wants to keep playing but you can't use "poly" or Kelvar. Can you find him a solution with these restrictions: 1) the setup lasts at least 10 hours 2)...

As an experiment, you can try YPTA and Swift crosses with Velocity mains. My guess is Swift will do the same and YPTA to a lesser extent.
My .02 on the guy using 1.35mm Velocity is to simply switch his mains to 1.30mm Lux Gut with 1.27mm GW crosses. He won't break the NG mains nearly as quickly, and the setup will be less expensive than breaking Velocity / GW.
I use 1.35mm VS Gut/1.27mm for several 4.0 male clients and it lasts them roughly 90 days before than break the gut.
Hope my comments makes sense. I think there is a Cream / Swift / YPTA thread and this should be posted there, but I have to catch a flight this am, so thanks again for the Klip NG deal. I owe you!!!
