I've got gatorskins on now, switching to gp 4-seasons just to try them out... both are available in 28s, no complaints here, though I do run them a bit harder than you are required to, depending on your size. I've been on them from 210 up to 245 and now just around 200 pounds. There's nothing wrong with the gatorskins, just was going to put them on my wife's bike, thought I'd try some new shoes just for the hell of it.
