We road OOP all last season. Had tried it a little before, but really went the whole season trying it. We seemed to be able to gauge our own efforts easier, OOP than IP. We don't climb standing. The Mrs. is more comfortable with the standing now, and we are working on that this year, so I don't have feedback on the climbing aspect. Like TG, we even tried mid ride to see how the difference was. Early on, we thought it was better, but by the end of the season, we found for us our performance was better IP. We did give it a solid try, and did like the feel. No issues cornering, as when my outside foot is down, stokers are level. If i lean the bike that much, I will have bigger issues than hitting a pedal! The biggest negative for us was that when we do coast, I have a tendency to coast level, lock the tube between my knees, which forces my stoker to coast one leg down, which was causing comfort issue for my stoker.
