**So this reply is focused solely on tangent aiming and my game.
Here's the thing. I can already direct OBs into tiny gaps with HAMB. I also have decent CB control that allows me to do pretty much anything I want as well... What this means of course, is that I have a good grasp of carom tangents and how to manlipulate them after the instantaneous result. To play 14.1 with even minor proficiency understanding caroms is a must.
Tangent aiming, at least for me, is just noise. Sure on the surface saying more information is better, but I do believe it reaches a point of diminishing returns. I would rather focus on the contact point that will slide the OB down a shot line rather than think about the tangent line that I won't know until I already have a grasp on the shot line. That said, if the OB has a wide open pocket to drop in and controlling the carom is paramount, then sure. ...but that's still not tangent aiming, just tangent consideration..?...lol
The tangent is the result of everything else that matters. In terms of aim, potting the ball matters. I don't care where the instantaneous tangent (90) is going to take me, because I know I can manlipulate the CB to where I want anyway.
