pull on, crux one, hit the top crux two
I'm afraid you're not making anything clearer.
That could be read as pulling on is the fiirst crux then hitting the top is the second
or as the move after pulling on is hard & so is the one after hitting the top.
Basically I've spent the afternoon not sticking the faint crack out right. I held it once, briefly.
If the next move or even worse the top-out are harder then it's not worth me going back.
On the other hand if it eases a tiny bit after then It's worth another pop.
