Pete, thanks for the write-up. I'd love to hear your thoughts on sizing; I'm 6'2.5" with normal proportions, and would pick an S5 in the Enduro and an XL in most frames. Do you feel that the XL you were on was on the big size of comfortable for you? XXL Sentinel seems like an absolute Sasquatch bike, but the XL is a tad shorter than would be my preference.
