It is worth trying. I would describe it as a system that a more visual person would love......because you can look at the cup, as you make your read vs. AimPoint obscuring it and shifting the focus to an exact spot.
AimPoint unequivocally works but for me personally, the way my eye focuses with my finger(s) in front of my face is just different than saying "Ok, 9 inches of break" and looking at the hole as I eyeball where that is. I find the visual read to be more accurate but again, a lot of these systems are preference.
Not everyone is good at reading with their eyes and that is ok........but if you have a feel for seeing the break direction, TourRead seems like a really good fit. If you have trouble seeing break, AimPoint does a great job providing a different tool for acquiring that info.
