Without using the high differential the Kevlar/Zx string bed is so stiff it is ridiculous. I tried it at 48/48 and not only was it stiff the playability was terrible. Guys are taking the same set up and stringing it at 60/40 and 70/40 and say that it plays well. I wouldn’t use a high differential to make Kevlar playable in my frame. Not worth it.I don't think that was the goal. I could be wrong though. If anyone using kevlar with a high differential embarked on that path as a way to make kevlar playable, please correct me.
The playability of Gut/poly or Poly/Gut is so far beyond anything Kevlar can produce. The whole point behind Kevlar is duration. The issue is how to make it playable and not destroy your arm.
I have always looked at what will help me produce my best tennis for 2 out of 3 sets and for my game nothing comes close to Gut/poly at $15 a frame.
Better combo meaning you would like better playability? There are many set ups with incredible playability out of that frame. If you are looking for better durability you may already be at the pinnacle with Kevlar. Something to consider is wear and tear on the arm long term.guys... been using this combo 16g Kev with 16g Natural ZX for like 3 yrs now... 62/52 on an PureAero... My son breaks the Kev in about 45 to 50 hours of play.... Love it but wonder if anyone has a even better combo?
The best tennis I see being produced with that frame is with full poly, poly/gut, and gut/poly.
