Now that these smaller bags have been our for a while, how do you feel about them vs the original versions? I will be buying one of these in the near future and it will be primarily used as a front support bag, but may see some time as a rear bag too. I'm kind of a weight weenie and tend to avoid unnecessarily heavy gear. Is the stability of the larger bags worth the weight penalty? Also, which specific bag do you recommend and why? I may get more in the future, but if i were going to buy just one, which should i get?
