I used to used the 105, 90, and 50 yard TM Satin wedges but I couldn't play the 50-60 yard shots that Charle mentioned. I dropped the 105 and added the Ping 60yrd wedge. Now my ranges are near perfect for me. I use the G10 irons, so my 9i is 115. I now don't have to choke down more than 20% on any club.
I've also started to play my approaches for a full swing wedge length to the pin.
