There's not really any way of telling. Try your current saddle, it might work for you. If not, you'll have to work your way through all the brands of stubb nosed TT/Tri saddles to find one that works (or is at least tolerable).
Thanks. Hmm, dammit, I was hoping there could be at least some kind of principle underlying this :( But yeah, I'll start off from a saddle that I know works on the road, and see how that goes.
