R8: V8 vs v10 and r-tronic questions

Which one is better, v8 or v10? I almost think I like the sound of the v8 better. and with a supercharger and exhaust it would be faster than the v10, and still come in at a much lower price… I think. Thoughts?

A more technical questions as well: Did the issues with the r-tronic ever get somewhat sorted out before they switched to s-tronic? From what I’ve read it seemed to be mostly how the transmission was programmed.

I think JHM tuned an r8 or two… would be nice to have more info.
