If looks was more important than function than I would not have moved the rack back- seeing as I did your statement is incorrect. Saying it looks odd is indeed an observation of form, but I am firmly a function-first kinda guy. Also it is hard to be vain when you are a 300lb man on a bike.

As far as function the weight moving so far aft changes the handling of the bike, but that negative is more than offset by the increased comfort of a normal foot position provided by the extra clearence of the movement of the rack allows. The whole point of this exersize has been to do this without any additional expenditures, and the current setup works perfectly in this regard.
