Have you had a chance to hit with the BB Hero? I'm hitting with that now and it's my first time with gut.
Compared to Live Wire XP and NXT ( both 16 ) it has more pop but similar feel and spin. I don't like the ping sound it gives off early on in the strings life but the sound has changed and is less tingy. I had it stung at 60 and raquet tune said 58 a couple days after yet still before the first hit. Three weeks later it said it was at 46. The bed looks pretty ratty and decent amount of string movement. I am pleased with the way it is playing still and will see how much longer I get.
