It's really a personal preference. I use velcro all the way up, but also don't feel bound to have it close perfectly. In ANH they do not, so I don't sweat it either. Also at my height (6'0 and long legged), I could never get TE-derived shins to fit me so simply got a set from RT and later TM instead. I'm impressed by all the work you are putting in - way beyond the usual.
