I have no idea what motivates non pro players to do what they do or choose to use what they use while on the pool table playing the game. It almost seems like they throw darts at the wall which are lined with the "technique of the day to work on."
But I think what most should consider is the SOURCE from where information is coming.
For my money and I think most is it should come straight from long time winning pro players themselves as well as certified pro instructors who have a history of teaching and success with the top pro players and amateurs at all levels...not to mention being nationally known and respected for what they've done in the game of pool as players, live instruction, and books/tapes/youtube videos.
If it's coming from a forum member, take it with a grain of salt. That includes me as well as everyone.
Since this thread was started as a NON-AIMING, NO NEED TO AIM thread by a forum member as taught to him by what I would consider a somewhat obscure local instructor in a small audience of the NW part of the country, you be the judge.
Here's Johnny Archer and Shane Van Boening discussing AIMING and how they do it at length. They differ, but it's a very important part of how they play and use it on every shot. Shane uses the shaft and different parts of the ferrule/tip whereas Johnny uses contact points. They also discuss how Stevie Moore has improved from CTE Pro1.

Willie Mosconi illustrates contact point aiming but refers to a shot as a fraction:

Thorsten Hohmann and Mike Massey: Go to 3:30. Mike talks about aiming at the contact point -

Stevie Moore gives a quick lesson on CTE:

Joe Tucker explaining his Contact Point aiming system. For the math guys and scientists, this is probably 100% geometrically correct where 100% of ALL SHOTS
will work using it. Not 40% or some other made up number pulled out of a hat:

I could go on and on with this all day. What I have NOT found is a pro player or pro instructor stating they don't use an aiming system of some kind or find them useless and JUNK.
Consider the SOURCE.
