I don't usually use an alignment line on my ball when putting. Heaps of pros do, so there's obviously something to it, I can understand that.

I've been fiddling around on my putting mat, and have discovered that I'm very good at putting a good, end-over-end roll on the ball, but not very good at lining the ball up.

How many of you use a line on the ball? Does it work? Does it annoy you from a pace of play point of view?

Any advice for lining the ball up better? I've got one of those Trident things, but didn't think it worked any better than just the ball by itself...
