Larson, Bozeman, Montana
I don't practice putting (or Golf) at all during the winter. My carpet is too long to putt on. I just accept that it will take a day of practice at the putting green to get my touch back.
My only real experience is with the ones at golf shops that are typically artificial turf over plywood. I did have the chance to use my dads mat once, but it was way faster than any greens I have ever putted on.
I would like to test the Slow 9-10 stimpmeter, this is likely close to what I am used to putting on and would provide the greatest benefit to training/practi
