I'm not replacing the saddle (Brooks) that I did the long ride on. I'm replacing the stock saddle on the Roubaix. My problem is switching back and forth. I've had the LHT/Brooks for 3 years. It was basically the only bike I rode. Got the Roubaix in Feb '14. Seat didn't feel too bad, but mostly shorter rides and started doing the Tuesday night group rides. I didn't ride the LHT for the whole summer, as my son used it to train and ride the RAGBRAI. Got it back late July and it felt odd. Took a good share of riding to get the good feel back. Took an 800 mile tour last month on the LHT and felt good. Got back on the roubaix and my butt was complaining. I know there are differences b/t the two that go beyond the seat, but I've got to get past the seat difference first. And since the Long ride supports a case for the Brooks, that is what I will put on the Roubaix. I assume I'm like many people out there that want to have a little variety in their riding.
