I consider all of my wedges to be a continuation of my irons. My PW is my 150 club, then my 52 degree wedge is my 125 club, my 56 is my 115 club and my lob (60) is my 105 club, all with full swings.
If I am under 105, I still use the lob, but take some off of the swing.
If I am chipping, unless I need to get it over something or have to have it stop fast, I always use the gap wedge.
From sand, I use either the 56 or 60 depending on the sand.
