Nope, I put them on nearly unaltered. I say "nearly", because what I did was take a little excess off near the wrists, where it would have overlapped and wrapped around more than once. Realistically I should have removed more material and shaped them more. I'm also regretting not getting them in stainless (which wasn't an option at the time, but Icefalcon has them now), because they're rusting around the forearm and wrist area.
While they're laced on, it's difficult to clean both them AND the arming cotte. And if I take the time to unlace and re-lace, it'll take almost as long as the first time around, and that was a slow and tedious process. Very historical though, if you ignore the fact that I used cheap metal eyelets.
There's a part of me that wants to get some stainless voiders, attach some heavy-duty velcro, and use that to quickly take them on and off. It's cheating, I know.
