From what you say, you play courses with very soft bunkers (56-14 being the clue) and you want to simplify your setup. You're going to get a bunch of answers. Some are going to tell you 48/52/56/60/64. Others may tell you 46/54/58. That is THEM. Ask yourself if the 52 is of any added value. I'm gathering it may not be if you intend on replacing it and the 56 with a 54. Why not p(mb), 54-14 and 60-07 (or even 60-10)? Or even stick with p (set), 52, 56-14 and 60-07 since that combo works (if it isn't broke, don't fix it). I use p (DCI or Eye 2), 54-11 (bent to 55-12) and 62-07. I used to carry 60-07 and 64-07 but traded them for the 62-07 because it does more than both put together (understanding I use it from 50 yards maximum; it also works in soft sand and hard sand and does the Phil flop shot). I tried a 48-06 and it didn't work for me (I had a hard time with it and the DCI P works better for me; traded for a 58-12 and returned that to the store because the 54-11 and 62-07 work better for me; I used the store credit to buy materials for a reshaft project on my Eye 2 irons). Then again, this is ME. I have a good short game but my style is pitching as opposed to bump and run (I use a 9 or PW on a chip shot when I have a long chip/pitch with a lot of green or when I get lazy and deem it less effort to take a 1/2 swing from 50 yards vs a choked pitch with the SW or a full golf shot with the 62).
