Well this thread got very bitchy very quickly!
OP, I think I have to make the decision based on the stats I have etc. As Lodden says I'm jamming on most regs, probably folding to nitty fish.
I don't think the fact that Sharkscope doesn't account for rebuys makes that much difference, in fact I only care about my own stats/profit and couldn't give a ***** about anyone else's. We all know how much we get paid each month.
