I feel your pain. I am the same way. Recently though I've realized that even though I change my swing, I either still keep some of the bad parts that cause problems or I'm not really changing it like I think I am. I have been videoing my swing and keeping track of what I'm trying to do and how the result was and I've noticed in many cases that I am really not changing my swing much at all. In other case I have changed it, but I still do some of the same bad things: poor posture, sliding instead of turning, losing control of the club at the top, too quick, etc. These things are my swing killers no matter what swing I'm shooting for. I've given up on different swings and just trying to focus on basics and trying to commit to the shot.....but not that's not quite working out yet lol.
