Sure it may heal faster but most ranges are not just one line of tees. They’ll have an acre of space to work with adjusting tees daily or every other day. Either way the tees will have re-grown with grass by the time the tees go back.
So generally, youd still want the lines because of not screwing that spot up so quick that others that day can’t use it.
I'd guess that any PGA player would look like he was in a major car wreck if he got hit by either Daren Bates or Donald Payne who are only about average PGA player height weighing in at a svelte 225-ish pounds.
I looked up "smallest linebackers" to find their names.
That was the key when I took lessons long ago and had to stop with that particular guy. In the lesson, he had me change this or that which I was able to do really well off the bat, but I did 3 swings and done. I couldn’t develop the feel of that change on 3 balls, so it never really stuck even with practice.
When using a swing aid, some help with eyeing a certain path while other aids help develop feel. Every student has their preferred method, whether its eye balling it or feeling it, etc.
