I can't remember exactly where I read it, but it stuck with me. At some point Phil was quoted saying something along the lines that he laughs at newer golfers/amateur golfers using a 64 wedge.
When I wanted a lob wedge I asked my father in law if he had an extra i could practice with, assuming he had a 60 degree around. Well he handed me a 64 and said I could keep it. I was intimidated...I knew what Phil and other people thought about the 64. Many people believe it's very difficult to become consistent with it.
The first week was rough, many shots were hit thin, many shots were flopped very high...but went like 5 feet. After putting in the hard work though and having used it a month+....it is now my favorite club. I think the trick for a newbie is to not open up the club face at all, you don't need to. Just accelerate through the ball and you can get a high arc...back spinning golf ball. Practice enough and I firmly believe that most golfers will have no problem putting the ball where they want it. The trickiest part I find is deciding how I need to hit the ball on different types of lies. Other than that, I'm loving it.
So basically, don't be scared, just put in the work
Edit: I don't ALWAYS keep the face close, I open it up a bit for some sand shots and perhaps depending on the lie and pin position I'll open it up a bit.
