Yesterday I was practicing after my lesson, when I decided to take a few swings with the driver, a 913D2.
On one of my swings I swear I saw a couple of sparks shoot up from the clubface at impact. I have no way to verify this of course, but has anything like this happened to any of you?
I'm not complaining or worried about my club, but it just seemed really weird. If they were really sparks, I must have just hit the combination of the ball and the tee "just right" to produce the effect. I'm sure if I swung my driver another million times, it'd never happen again.
