Mt, the same thing happened to me! I walked into a bike shop, not knowing anything about fit and not wanting to spend too much money on a bike I wasn't sure I would ride. I also ended up with an OCR3 that was too big for me, rode it a year and finally figured out it was too big. I now have a WSD bike, and it's much more comfortable, and I'm much happier. Ride lots of different bikes, pay for a fitting if you have to, and read everything you can get your hands on (there's a ton of stuff here). The bottom line, though, is fit. It should just feel right, like slipping into your favorite pair of jeans. Good luck and let us know what you decide.
