I do have Gatorskins on my roadie trainer, 700x25c, and they're no harsher than my GP4KIIs that I used prior to that. I didn't care much for the gashes and punctures that GP4KIIs gave me over only 2K miles, and was hesitant about going back to the Gatorskins, but so far they fare well. I agree with checking the psi though, that could have something to do with it. Go low until you pinch, then go higher I suppose.
