I completely agree that its not a club for every shot. For me if the ball is within a yard or two.from the green I will chip (unless i need to carry something). I probably would say I pitch around the greens 80% of the time. I'd say I use my 58 degree wedge 90% of my pitches. I will use my 54 or my 50 depending on the lie or distance of the shot. All I am saying is technique is what allows me to use any club. Using the quickie pitching technique I can hit all different trajectories with different amounts of release. So for me I can do more with my LW. I know everyone has their own ideas and I'm not saying your wrong but I use my 58 way more than my 54 or 46. I wish I didn't have to use it so much buy my long irons are atrocious
There really is no "wrong". Just different odds of success on different shots for different people. Playing our best odds on every shot is all we can do unless we improve something that changes the odds.
