I was told the infinity's in 3.5lb are really forgiving
I have the chub outkasts in 3lb TC and there quite unforgiving compared with most other wands... I think grays in general are quite stiff
When you need to play big fish through HUGE clumps of weed you really do need that extra umph
I would have a chuck with them but I don't really stray to far due to transport

But if your fishing any place near me then tell me and I'll come down
Ohh and by the way thanks for the offer aswell mate =]
