Frankly, I don't understand why people struggle with using a 60° wedge.
IF the 1/2" per club idea is the logic behind why short
irons are 'easier' to hit, then the 60 should be the easiest. (So obviously it's bunk).
If it's built properly, the 60 is no different than any other club - in fact, most 60's are only a gram or two heavier than your GW or PW - you should, in essence, have more trouble swinging your SW than your 60, as it's up to 12g heavier than your PW.
I say it's totally mental. And I love my 60. The only place I find a 60 is tough is when your ball is fluffed up in long rough - then, at 60°, it's far too easy to slide the face under the ball. Anywhere else and it's just as good as any other club... save maybe a driver.
