Comments: I use a Kfactor 90 and BLX 90 which are relatively stiff compared to other racquets. My arm has been
feeling bad; however, I used this string and it gives me great feel during impact. Really soft feeling as well as really close to the gut
feeling. The feeling is totally a plus for anyone uses this string to play. Durability is not too good which is pretty obvious since it is
soft multi. After probably four times hitting heavy, the string start to peel off the outermost layer. But it will still hold for a couple of
more time until only few thing fibers hold there. It is the best string I ever hit and if you don't mind the cost, go for it.
