So I registered for the Ergo baby carrier but just noticed there is also an "Ergo Sport" version (in black with white threading). The Ergo Sport version looks newer and is supposed to have longer adjustable shoulder and waist straps and made with more "breathable" fabric. I've tried to search this board as well as via google to see comparisons/reviews but haven't found much.

So I'm puzzled as to why this "newer" sports version is being sold cheaper at around $95 while the original version continues to sell at around $105.... am I missing something? How come the sports version is cheaper? Anyone care to comment if they've bought or tried both versions as to which one is better?
