I doubt whether it's really valid after everyone else's opinions, but I'm running BC BR RA's (pretty sure, no camber tops on rear), and I've never had an issue. Went from stock Gen 2, to Gen 3, to the BC's, and the difference is MASSIVE! Running 12 damper front, and 14 rear, with Whitelines running mid-stiff both ends. Handles like a dream in the hills, and works well for track, steps out a little, but it's predictable and easy to control! Never bottomed out with the 6 and 8kg springs, and I was taking it out 3 or 4 times a week til recently.
From the research I've done, they're excellent value for money, good quality and will have a good life (I bought mine second hand at a year old).
Don't really know if I could justify going the RH's myself, but it really depends on what you, personally, are after. The differences will just allow you to be a little more anal about your alignment, and may get a little more life out of them. If you're only weekending or tracking it, lifetime isn't really a huge issue regarding general wear and tear though :)
