I want to install a hook in my bathroom to hang my strop. What height is best for ergonomics? If I put the hook at elbow height, then the strop will be horizontal when pulled taught. Or if I hang it a little higher, it will rise up a bit. Or I could hang it even higher and give the strop a 45 degree, or even steeper incline when pulled taught. I wondered if there is a consensus as to the ideal slope for the tightened strop?
