Make sure they fit first...there are two models now, so try on both and see which fits better (if either...maybe they both don't fit). Then, realize that there isn't much difference between the boots...basically, it's the liner, flex, boot board, and buckle type that are different between the boots. You'll probably want a 6 or 8 flex (maybe even a 10 if you charge really hard), and you'll definitely want the Pro Liner (top of the line liner and it's amazing - well worth the extra cash), as far as boot board, that comes down to preference, do you want the shock absorbing active boot board or the rigid boot board with more feel of the snow. The buckles aren't that big of a deal, it is a bummer when the plastic breaks, but I wouldn't base my entire decision on the buckles. Also, remember that all the parts are able to be changed out and customized with "after market" parts.
