budfan4861: Still struggling with the vertex method. Don't completely understand how to use it to set my aim.
It's probably the easiest and quickest method to use ;). Take a look at Tekoma's Video, Part 2 and you'll see that he makes an "initial" read of the break based on the flow of dots. He uses both reverse and forward view, but not limited to either one (depends on the hole, view, break, etc).
Then once you've approximated where the break should be you move the aim box from hole level and drag it along the same line to the end of the putting grid, at which point you then place the aim box (arrow) on the closest corresonding Vertex (long straight Vertical line at end of grid) or center of the grid square (end of putting grid between 2 vertical grids).
At this point Tekoma zooms back out and clicks on the aim box/arrow a few times and visually verifies he is in fact on the correct vertex. All thats left is to pick the correct speed and the putt will either be very close to in or in the hole!
It's really a brilliant technique and works especially well on long snakey multiple break putts.
