Bars?

Which bars would I be better off with? I've got a long torso, but short arms. I'm looking at either a pair of pro-tapers('98kx250 bend, middle of the line rise and sweep) and a pair of renthal fat bars(RC bend, high rise and sweep). I'd also be using them w/a pro-taper mount kit(the one that attaches to the existing bottom bar clamp). I've been having a problem w/arm pump and I want to see if this will help. I am currently using a renthal bar(don't know the bend) that is taller than my stock one(not quite sure on the sweep as it's a little bent. it's not mine, just borrowing it from my buddy(his spare)).
