I'd vote the 520,you'll spend a little more (maybe),less aggrivation if you would have chosen the e-bay used route, for example you'll end -upwith TWO bikes,better than ONE bike a nd parts, the Bike will work better. You'll like the 520 for more than touring anyway, have it for a buddy, he can use it ,you use the OCR2 or visa -versa. OCR2s have very nice componts and wheels for fast rides,why sacrifice that ?
