So I've been think of jumping on this IH/dwlink bandwagon for my very first full suspension bike. I'm wondering when the differences in the Hollowpoint platforms start showing up. Call me a ridiculously vain bike whore, but cosmetics is the main thing I'm concerned about. In particular, I like the look of the earlier versions w/ a horizontal shock position v. the later ones w/ a vertical shock. When was the switch in designs? How significantly different are these frames? I'll be using it mainly for long, aggressive XC rides (I'm not sure if I am physically capable of long, aggressive XC rides, but at least my bike won't be the excuse anymore).
