Buckeye8084: I'm trying to find out what are the advantages of carrying it
I can see why you choose the wedges you already have - with the Burner irons, you need them. When I had those, I carried 4 wedges and no 3 wood for a while, to cover the 'gap' between the Burner PW and and the CG 56 degree, 100 yard club. If you choose G20's (level 83) or later the R11 irons, that gap will be eliminated; in fact with the G20's I dropped the 56 and carried the hybrid, as the G20 PW eliminated the need. Now, with R11's, I carrry the 56, 60, 64, as do most players with R11 irons, plus a 3 wood.
As for the 60 degree, it is just a farther hitting version of the 60, both being lifesavers under the right conditions. With Nike balls, full shots to 85 yards, punches to 68-70, pitches 25 (full bs) and chips to 10-11 yards (full bs). It is a very useful club!
