yeah, i should have a pro fitting done. if there is a discrepancy with the length of my legs, it is a minor one. And it hasn't been much of a problem, but something I was curious about and thought worth looking into. I do get minor aches in one leg and not the other from time to time. Nothing severe, but definitely noticable. I've always chalked it up to compensating for minor leg length discrepancy. While I definitely appreciate the concern, I don't think it's something I need to see a doctor about. But the pro fitting is probably a good idea. Especially for when I lose my mind and blow all my savings on a custom frame!! woohoo!
