It's my first winter with a sim. Historically, I avoided driving ranges with mat's. I'd visit an indoor place a couple times a winter max. Now I'm hitting balls 5 days a week in my garage! Curious any insight or experiences. For iron's, do picker's do better than digger's on the mat and returning to grass? Do digger's either quit or become picker's? Anything you choose not to practice much off the mat (chipping, pitching, half wedges). Its going to be a couple more months before I get outside to find out for myself.
