I use the arrows, but have been practicing with targeting the breakpoint. Using the arrows, if I miss, it tends to be inside, and I tend to miss inside way too often, so I am trying to change.
I have nystagmus also, but my contacts are toric 66 and are designed to address that issue.
I think I will end up using the arrows to line up, but ultimately focusing on the breakpoint downlane when I start my approach.
BTW, on the old wooden lanes that I bowl on Wednesdays, its the arrows and feel as you really can not concentrate on one bland colored board 43 feet down the lane. What a pain.
