thanks for the info, guys. i don't know whether the snake-eyes windows are available anymore on the Big Mike models. i measured the height last night with a measuring tape at 80", and the bottom window appears to be at least 40" up. i sat in my Huntmore chair with the legs fully extended, and i could just barely clear the lowest part of the window from there, seated.
sure wish the windows were a little lower. kinda messes up your upper limb clearance if you have to stand up.
i do appreciate all you guys weighing in!
