Very smooth feel, nice blend of power + touch. Seems to hold tension very well. My daughter switched to this string 2 months ago from Kirshbaum Pro Line II 17G. She says they have a more "solid" feel and that she feels the ball better. Her coach had to talk her into trying them, now she won't use anything else. She is a solid player, senior in HS (all state) and will play DII or DIII college tennis next fall. She uses a Wilson Juice Pro BLX, strung at 58 lbs.
