ohh, I had such a bad experience with the Bio500T.
Looking back, I probably didn't give it a chance, it was strung with Silk and was probably at abour 60lbs, like yours.
For me, it was an overpowered and rather unstable cannon of a thing that I just couldn't get to grips with.
I probably should have restrung it with a soft poly at a lower tension, but I lost a match to someone I should (and always have before) beat and sold it the next day in disgust..
Everyone likes different stuff is all you can really take away from this place, eh?
