It really isn’t a faff. One of the IS holes is slotted (or was on mine) so I just loosened the bolts, swung it out of the way and nipped up the bolt it rotated around so I didn’t have a loose brake calliper hanging around. Quicker than unscrewing a normal axel, and certainly quicker to put back on as you don’t have to line the disc up with the calliper, you just put the wheel on the axel, tighten it and swing the calliper back on the disc – it’s already lined up.
The only thing I was concerned with was over tightening the allen screw to attach the wheel to the axel as I can be a bit heavy when tightening things up. I never did as it happens and read on various forums about people who did and it’s an easy fix with a helicoil, so again, doesn’t appear to be a major problem.
