He has some real goodies on that site eh? It took a bit longer for me to get my stuff as it's a one-man show but since I'm sold on friction-only from now on I'm gonna go with them.

I have a some DA shifters hooked up to a 9 speed rapid rise and it works fine... in fact, it works on the same direction as downtube shifters so if you're coming from those it's same. I've never actually used bar-ends with a normal derailleur but I have a sturmey-archer bar-end and it still trips me up sometimes.
