Well, no answer on Rodney Morris endorsing cte before.
Wasn't Darren Appleton endorsing the SEE System one time too.
When US Open winners start endorsing aiming systems they've never heard of before they won their major titles, the endorsement is kinda doubtful.
It's kinda like Allsion Fisher and Jeanette Lee endorsing some expensive laser gizmo.
Lol. Good point. And it doesn't mean that aiming systems are junk and not beneficial to players looking to improve. It just means those pros didn't use or need the systems or gizmos they happen to be pushing.
