I Tried the TB soft couple of months ago and it is by far the best sting ever for me!! Yes it is much softer VS the original TB, not as crisp but very comfortable. If you have litle issue with your arm that string is a lifesaver. I just tried the RPM this week to compare and there are no comparison in my opinion. TB soft all the way. Better control, not mushy after 1 hour, no plastic feel, alot of power. Its gonna be a big winner. My ball was always little short with the normal Tourbite, now with the soft it is couple of feet deeper. I got a reel of 17 soft. If someone wanna try just send me a email. Of course this is my personal opinion about the string and it always depend of your style, racquet, tension etc. Some persons will love it and some won't!!
NTRP 6.0 and Tourbite soft at 38/40lbs!
