When to use your 54 and 58 degree sand wedge around the greens.

I carry a 54 and 58 degree wedge. My 58, or lob wedge, is an emergency club around the greens. I’m only going to use it when I have to hit something higher and stop it quicker than I can with my 58. I use my 58 all the time in my distance wedges. Want at least four degrees of separation in lofts in your wedges for distance control.
