Are SPD SL cleats better for long distance touring? Nevermind walking on cleats, I'll pack a pair of sandals in my messenger bag anyway. In terms of flex, and comfort, shouldn't SPD SL be better for distances over 50 miles? I just got off the chat with a rep from nashbar, and he told me two bolt and three bolt is night and day difference, and that he recommends three bolt for touring.

That's my question for now. I just want to get this cleat situation figured out, so I can order my shoes, and start working on my physique.
