The hard part is all up front. The first solve you do is the hardest, it took me 30m+.

I'd also recommend learning M2 over OP for edges. I used Noah's guide back when. M2 is so much faster, that unless you are going all the way to 3 style (which is a large jump) M2/OP is pretty optimal. If you've got more questions I'll try to scan every so often.

The OP (old Pochmann) is a super simple method. Learning 3bld if you can already solve a cube is actually less work then learning to solve the cube at first
