4 degrees of loft is usually the standard amount of loft between clubs in an iron set. Most PWs are around 47 degrees so, the 48 def. won't fit most bags unless you ditch your PW for it. I prefer my first wedge (GW) @ 52 degrees... That said, still an amazing looking set of wedges.
btw. I also don't think its's necessary to have that grind on a 48 degree iron. Leave it to the 56s and above, when you really want to open it up and hit the high flopper.
