Here is the deal... I mainly wanted to take Aimpoint for a few reasons...
1.) I was playing golf here in Socal a little over a year ago - maybe 1.5yrs ago? I was a single and got matched up with a few other guys. One guy was using his Aimpoint chart and getting reads on putts, and no kidding - draining a lot of putts. I was pretty impressed with how this guy was able to make what I considered difficult putts - at lengths that were beyond the typical make range of an amateur player. And more importantly, his misses were all within reasonable range tap-in to shorty par save range. He didn't have a 3 putt, and easily his putting was the best part of his game.
So I did research after that round, looking on-line to see what I could find about Aimpoint. And I contacted the local Aimpoint Instructor at the time in San Diego (who has since left Aimpoint)... And got pricing. When I received the pricing, I too was skeptical, and didn't think it was worth spending the money. So I passed.
2.) I attended the Callaway Ely Performance center in Carlsbad, CA last Summer. And during the Ely visit, we met with the guys in the Odyssey putting lab, where they have a SAM, and were discussing the effects of being aimed properly, and the capture speed of a putt. All of this talk about being aimed properly - and its effects on how far offline your putt could be based on the length, really made me more aware of the 'science' behind putting.
Here is a chart that was hanging inside the Odyssey lab for example (sorry it is a little blurry - but it was taken with my iPhone).
3.) Being a regular on this site, and talking to guys about Aimpoint, made me more and more interested. So when Erik, Dave and Mike organized an Aimpoint clinic last Summer, I knew I had to take advantage of it. First, to get a chance to meet Erik and Dave (I'd already met Mike)... But also, to finally get a chance to learn Aimpoint.
The thing I like the most about Aimpoint, similar to what Golfingdad mentioned in his post... Is that it helps my confidence level. I get my Aimpoint read, and simply look the number up in the chart. Once I have the number, it helps me as I'm confident that the number is pretty damn accurate. Especially on long putts - I know it is going to give me a solid chance at a two putt (possibly making the putt) - as long as I get the putt rolling at the proper speed.
But the other thing that is really cool about Aimpoint... Is that you can really learn how to hit those testy 5ft severe breaking putts. Ones that you only see Pros make... Watch this homemade video for instance... This is a 4% slope - and using Aimpoint to get the break. Once you get the break, it is just knowing how hard to hit the putt - which is still instinctive - but again, takes at least the guesstimate piece out of the equation.
