I'm having a difficult time figuring out when to use which technique. For example, when does one use centering the flag as opposed to centering the hole? Any help would be appreciated.
Line the putt up as you normally do... Chances are your normal read will be very close to one of Tecoma's "reads" and then you will quickly know which one to use.
I only use center ball, center cup, front and back of foot. I don't understand the vortex line one.
