I still use one. I have used a long putter, off and on (mostly on) for +30 years. Started in college. Way more unique back then. Frankly, I am putting better now unanchored with it then before. My club is no where no near 10% but we do have a few who still do it. Also, have a few side saddlers. It is not how but how many I have settled on a 2-ball but have over dozen long putters that usually get out for a round or two during the year.
