Not sure what you mean about DA 8s, but low-normal (Rapid Rise in Shimano speak) derailers are
perfectly compatible with everything out there, except that the printed numbers will be reversed.
The first several derailers I owned (Benelux Mark VII & Makr VIII) were all low-normal, and it
really is a superior system.
When parallelogram-type derailers first came in, back in the late '50s, nobody could figure out how
to make the linkage work low-normal, so they switched to high-normal.
The parallelogram system reduced friction so much that it created a net improvement in shifting,
despite the fact that it shifted the "wrong way."
Now Shimano has figured out to give us the best of both worlds. It is true that it takes some mental
readjustment to learn to shift in the opposite direction, but the improved performance and
convenience is probably worth it in the long run.
