Learning nerve placement is an overlooked aspect as well. Most people think of falls and circulation as they are very visual. But I knew more people that got hurt from nerve compression than falls.

I tried fairly regularly for a few years but haven't in the last 5 or 6, so my memory is a little hazy. I mostly recall using it for locking off crossing lines (on a harness or what not) so they don't shift. I can't recall the harness names now might have been modified TKs? IMHO it looks better than lines crossing at 90 that just lay on each other.
For suspension / up lines it was always half hitch with a couple extra turns at the ring with a Y hanger(?) or single column around the ropes or carabiner hooked to the ropes.
*Brain fart, yes lock off was a munter followed by half hitches.
*The futumomo I usually tied had munters too now that I think back.
You don't need to know a ton of knots. Somerville bowline, munter hitch, half hitch, and reverse tension will get you pretty far.

One thing with Munters that was drilled into me was also making sure you're using closed and not open munter hitches since the open ones can shift.
