I am trying this string right now. It's been in my racquet for 3 weeks now. Strung as mains in a hybrid with Prince Premier Attack 16, both at 50 lbs.
So far, nothing special. Felt boardy in the first week, like all polys do. Then it loosened up, but just a tiny bit. Control is great, but I do not feel the softness. Even the regular softness is not there, compared to other polys, let alone the "plus 38 percent" of it. Nor do I feel the extra power.
The disappointing characteristic (for me) which stands out is that the harder the shot, the more dampened the response. On touch/slow shots, the string yields and springs back nicely -- as you'd expect, but on hard shots it all stiffens up on you -- very unproportionally so.
Maybe that's what it is designed to do. Maybe it is meant for hard hitters who want control in hard rallies and a bit of give on touch shots.
Spin is very strong -- no question about it.
Feel, resilience and softness appear to be missing.
Will try it later at much lower tension -- 44 or so.
Interested to hear what other's impressions are.
