Doc H, your post was rather timely! But for a slightly different reason. I was going to ask whether anyone else had tried deliberately to bowl with their eyes closed or without their glasses (without my glasses, anything beyond an inch in front of my face is a blur).
My wife and I both tried this yesterday in one game (practice, obviously, rather than in a competition) as we'd read something along the line of how it can help develop better feel. It worked quite well for my wife, though less so for me. The general technique was to take just the last two steps with eyes closed.
My wife commented that it seemed to take the pressure off the aiming which in turn helped her release more cleanly.
To me, it seemed a good confirmation of the importance of muscle memory. Assuming a consistent approach and swing, one shouldn't even need to see the target line to deliver a reasonably accurate ball.
Any thoughts?
