cpw, i was kinda in the same boat. i though a 54 or 55 would be a good fit, but i ended up with a 53 giant ocr elite. the compact geometry makes it look very small, but it does fit well: the top tube isnt too long and i was able to adjust the seat to about bar height. even though it looked small at first glance, it really does fit well and i really like it. lbs assured me he wouldnt sell me anything that didnt fit right. they were right, after a couple of adjustments, ie moving seat forward and switching the stem to upright position it rides like a charm. rest assured, if you feel comfortable on it, you made the right choice. cheers.
