My wedges look a lot like TnGolf77's mix. I have a 48 that goes up to 120, a 52 that is up to 105, a 56 that is a 90 yd club and a 58 that is up to 75 but is mainly a sand club. I have a few key yardages that I have a swing and a club for, (not necessarily a full swing but one I know I have.) I have a 115 yard shot with the 48, a 100 yard shot with the 52, a 90 and a 50 yard shot with the 56. (The 58 will go 75 full, but I would rather work off the 50 or 90 yard swing with the 56 for that distance.) I just work off those few distances with those clubs to range my scoring shots. In my head its just a little harder 50 yard shot for 65, or a little easier 90 yard shot for 75.
Learn your wedges, break your grooves in and then wear them out, (your wedges and your opponents)
