I just came back after what (according to a trophy in my list) could have been 5 or 6 years.
In 1 week I've managed to add 10 shots to my average. I was never a chart/calc type player, I've no problem with those that are but I just like to glance at the details and swing. It turns out that's a hard thing to get back to when you haven't got 80+ levels of learning to recall. I'm sure I used to rely on putting to compete and that's now the hardest part.
Might it be easier to just start over.....
*On the plus side I still think the golf itself is as good as anything out there (if a tad expensive).
