Hi Easy,
regardng J 10s pf raise:
I would think a factor would be whether you plan to also bet the flop no matter what as the PF raiser. If you don't hit, but bet 2/3 of the pot every time in the hopes of taking the pot wthout a fight, it might get expensive if you only hit your straight or flush 10% of the time and people play back at you. If you don't bet the flop after pf raising, doesn't your table image suffer and your pf raises lose meaning? Does it matter?
