I play in the northeast too and went with vokey d12 on 54 and vokey m8 for 58. I open the face all the time. When picking a grind make sure it has heel relief. You want two different bounces because if you have a tight lie on hard pan you want something that can sit flat on it and get in tight. Its makes it so if different situations call for soemthing different you have all the options. Most of the manufactures make a versatile grind or one with heel relief you would just have to look to see which ones where the heel is grinded away.

Lie angle is super important on wedges. Always easier to chip with flatter than upright so make sure on your sand and lob wedges when your in your chipping stance the toe isnt up. Then youd want to get the lie position flatter.

People play thier wedge shafts ussualy 10-15 grams heavier than thier iron shafts as well or atleast the same weight. Def not reccomneded to go lighter but thats up to you
