I don't know man, I'm a 009 guy for 25.5" scales, but when I bought my first JP(12) I setup for 09 and it was a little too soft.
Playing other JPs later, setup for 10s, what usually is a little heavy for me, it was sweet. Even though this is personal I think the JP's somehow are better suited for 10s. When I play a strat with 10s I feel my tendons pulling a lot of weight, in my other JP is just fine.
