Aimpoint is not slow, more often than not, you can be doing your read by standing over you ball, while the others stalk both sides of the hole, if anything aimpoint speeds up putting.
Nonsense, I wasn't a bad putter before aimpoint, but after I've become a much better putter, don't remember the last three putt I made now. I agree about putting practice, but that is the same with anything including aimpoint, the more you do it the better you become.
Aimpoint doesn't use green books.
For me as I've written in other threads, Aimpoint works for me, for others who see it as snake oil, they will never use it or try to understand it, so they will always be hostile towards it.
As is written above, there is no grey area when it comes to aimpoint, it's a marmite subject, like it or loathe it.
