Yeah I've heard and read some great reviews on the PSSs. Quickly checked tire rack for the potenzas and they don't seem to carry my size.. Odd. Maybe I'm looking at the wrong submodel (11a?). Either way, I'm pretty set on the michelins. I'd LOVE to get a tubi exhaust but I already have a Dinan exhaust from my previous owner and I quite like it. The tubi is like 5-6 grand, no? Yeah, not worth it to me.
