I'm actually considering a Trek Marlin. I believe the whole smart wheel size is to deal with standover height and toe strike issues. I'm on the other side of the argument, where I'm only 5'9 with a 30 in inseam. The thing with me is, bigger wheels roll over things easier. Learned that as a inline skater. I also believe the bigger tires will roll faster. If your not riding aggressive trails and your worried about weight, have you considered the trek DS. I would like one of those, but I occasionally ride a very technical trail and struggle with skinny tire size. Hope you find exactly what you want at a discounted price. If you buy something, please post pictures.
