braking
My experience is exactly the opposite. Even with fresh shoes and a pretty decent hub, my slash 5 braking is not as effective as my /7 was with ATE's. But then again that was a dual ATE setup. However, I didn't think that the ATE's were really up to snuff so I converted to a dual Brembo set up. IMOH much better and a lot less fiddly on the set up.
I don't think the single disk ATE setup will out perform a properly set-up /5 drum setup. BMW had to use a disk for style reasons given the new Japanese competition. But the wisdom in 1976 was that the brakes were not as good as the /5 drum set.
