Nice blog!
I've been using CTE/Pro1 about the same timeframe and my experiences were similar. There was initial confusion with the DVD, which was quickly put to rest thanks to all of the great info I found on here, or received from members, or from Stan himself. Then the initial learning, followed by figuring out when to use which aim point/pivot, then integrating the Pro1 pivots into the mix.
It's all very seamless now, on most shots I doubt anyone would even know what I was doing since I don't think it's real obvious what I'm looking at and the pivots are done on the way down to the shot. The whole process is just as quick as it was before when I would just stand behind the line of the shot and aim my old way. I find for certain angles, or long shots, it does help to stare a bit longer, or get down on the shot more at eye level to pick out the lines, and even then it doesn't feel weird or anything. And I still feel like I keep getting better at picking up the visuals more and more naturally. If I played more than 4 - 6 hours a week I'm sure this whole process would have been vastly shortened as well.
I've also transitioned to using BHE on most of my shots when adjusting for english, something I did more by feel before. Switching shafts has screwed me up recently in this department, but I'm getting through that now. I feel like I can aim center ball and then make whatever adjustment I need for CIT, position, etc. in a very systematic way while still allowing my 20 years of experience to supplement that and make tweaks as necessary for certain speeds/spins. That's taken a while, at first I trusted the system too much, then not enough, and now there's a nice blend where my eyes will usually tell me if I'm not quite lined up right, or made a bad pivot/move down to the ball, etc. Now if I can only learn to get back up instead of fidgeting on the shot once down I'll probably make even more shots...
Thanks again for the post! I liked your spot system info too, especially for kicks, I mention that quite a bit in the articles I've done on kicking, it's a powerful tool for making adjustments when not on the ideal line.
