I'll use my 56* 90% of the time from a greenside bunker.
I don't carry a 60* wedge.
OP, i think you want to say 'various lies', not 'lays'. Usually when used like that 'lays' refers to sex partners...'i had a great lay last night', or 'let's get laid every night in Bangkok'. Golfers prefer (well, on the course at least) the various lies, or positions of the ball on the turf or sand, whatever.
Me? I like my 56* sand wedge out of the sand. I read that Elin Woods preferred the PW when she laid into the car window. Tricky verbs, eh?
What? That just shows how little you really know. If you open it to 90°, the ball goes straight up and straight down back in the bunker - never moves forward at all. Wow...
Not far enough to do any good. If you open a clubface so it's dead flat, the sand and ball will pop straight up and down, with friction causing only slight forward movement at most. Anything else defies the laws of physics. Some of you may think that you are opening the face that far, but it's an illusion, not reality. I'm a fairly decent bunker player and I know how to play that shot, so don't let that 16.8 handicap I've posted fool you.
Dude, he's 14...don't argue with him. You and I might be engineers with physics knowledge that he could only dream of...but...
Which, as I'm sure you'd agree, has absolutely nothing to do with "friction". lol
