When it comes to putting, the line is 3rd on my list of problems
My biggest issue is hitting it square. Even if I read the putt right, there is a real good chance I push the putt. My second issue is speed. I very rarely miss a putt left or right. It is usually short or long. On top of that, most of the crap courses I play have pretty flat greens. My main focus has been on hitting it square and at the right speed. When I do that, even if I misread the line, I'm close enough for a tap in. That said, when I was actually good at golf, back before kids, this would have been great advice.
