Problem #1 - Hard to grade because it a 1-move wonder. If I had to guess, I would say V6/7. There is a sit down start that adds ~12 feet of dead horizontal climbing that should come in at V11/12.
Problem #2 - The direct start to another line. It suits my style, i.e., crimp & go. V8/9.
Problem #3 - The alternative start/link-up to another line, very nice movement and might be V9. The direct finish is harder.
