I have a Drakon on my road bike…it's the first ever saddle that gives me essentially no problems on road or trainer. It took me >7k miles before I found my saddle(s). I now have SMP saddles on my road, CX, and tandem (Lite 209 on the tandem and and a Glider on my CX bike). Not sure I'd ever bother with the mtb, since I'm not in the saddle or pedaling consistently, so I've never had the sort of issues that I do on the steady-state pedaling bikes.
