2nd gen brake options?

[revhead]

I've pretty much decided on my front brakes. (C5 stuff w/ Kore3 billet hubs)

Now the rear brakes are what I am trying to plan out.

I want to make sure I have a parking brake and I don't really like the idea of using 2 left hand calipers.. I now it doesn't really hurt anything, I just have this symmetry thing and it will bug me. I've also thought about using a pinion mounted parking brake if there is such a thing or if there is enough clearance.

So

between LS1 rear brakes and C5 brakes what would you guys choose? What has to be done to use a RH and LH caliper?

I just picked up some 17" ROH rollers and plan on using 17" VWW V48s in the end so I need the brakes to clear them too.
