love the vcore 100s. Have played with it w/gamma zo rough 16 (THe orange stuff) and liked that pretty well too.
I had a RQiS tour 2 that I strung at 56 and it felt pretty loose too, but I agree, I got a little over enthusiastic. Verve seems to string up a little tighter too....
In my defense, back in the day, I would string my Prince 110 at 74 lbs w/ no problems. Who knew 10 sq. in. and 25 years of age would make such a difference! heh heh heh
