So I locked in a carbon fiber shaft that I really liked the feel and hit of, bought four of them in three different joint pin types, and two lengths.
I then bounced around with different butts but settled quickly on 3/8-10 flat-faced ivory vs 5/16-14 steel pilot. I found that at my skill level, the softer hit of the ivory was not working well, so for this session, I'm only playing with a 5/16-14 compression joint.
I mention this only in the context of Lou's point on NCS. Each time I changed butts, I found there was a period of perceived better play, but in the long run, it was not sustained.
I agree with what folks have said above, you switch equipment and you focus more until a comfort level is hit, allowing bad habits to surface again.
But there is also a factor where when you are switching equipment out so often, you are not developing good feel and muscle memory that is crucial for this game.
