do they actually measure for the 7" seam? i bought some a while ago thinking i would be ahead of the game and they ended up being 8"
Don't get so uptight about this sort of stuff; if some DI measures and says they are too long just tell them you didn't measure them, you just bought the shortest pair you could find that didn't result in you exposing your junk. It might mean a few more pushups and unwanted attention at a few Plebe Beats during Indoc, but your "rep" will be made and safe for the rest of the next four years.
We are less than 60 days away from the new class reporting. This "sweat in' the small stuff' is ALL I can do. I would quit if I wasn't enjoying it.
