I think a 64degree wedge is your best option..they are great for around the green,particularly the pitch off of everywhere but the fringe..(even then if enough distance to the cup 4yds+)..I rarely use the chip as I like less green travel to worry about
I use the level 41or42 Ping 64 which seems to be a solid club to me..some of the best in the game are still using it even though they have their pick at their level.
Good thing to have one wedge where the spin is not as scary as the Cleveland ones for the very short game.
Max distance is about 63yds with topspin..,minimum (with accuracy) a 7yd chip rolls out to 10yds at full power no spin on a flattish green from the fringe...and as low as 4yds can still be very accurate by reducing the power used and the spin.
Using less than 70% power with a wedge throws the accuracy out the window imho..so having a club shot closest to the required distance is a good thing.
Mapping out the different ranges of all shot choices with your wedges at various strengths/use of spin..,and taking notes being the best way to go forward..I personally use #2 at Congressional on the single hole option for practicing around the green.And every 9th shot i just cross the page and hit "play hole now" again.
I would say I am not an authority on the game by any means,and still learning daily..but hope this helps.
