It depends.
Two seasons ago I was in between careers, and worked part time at my course as a pro-shop attendant. Read this to mean that I played quite often - dropping my index from 20 to 13. During that period, I could hit several different shots with a 50* PING iWedge. I had that "feel" we all talk about.
This past season I was full-time gainfully employed again; didn't play too often and the index creeped back up a little. I did not have that feel anymore, had new clubs in play, etc. That 1/2 50* option wasn't available.
Reacting to that, I used the bump and run more often. I figured the smaller the swing the better, and it worked out.
I recognize this as a Band-Aid though. Pursuit of key four with little swings will likely yield that feel once again. IMHO - players need a go-to chip (bump & run) as well as a pitch (50yd) that can carry trouble, etc.
