When the ban came in, they were directing towards a very small group of hot players. Other players were complaining, saying they got advantage from using said putters. I’ve used all, belly, arm, & broom. Like I said when the ban came out, you have to practice with each to be good with each. Those pros spent relentless hours, like other pros with normal putters, to perfect each styles craft. I didn’t really give the belly long enough, didn’t like it. The arm lock was ok, couldn’t get that decent from long range. The belly is where I found the most success. I felt relief on my back after rounds, while using the broom. Short putts were dialed in rather quickly, took a bit for lag putting, but it came around. In one Mens league I play in, a guy in his early 30s uses a side saddle & is deadly. Another late 20s uses a broomstick & is good. Different strokes for different folks. I’ve never had anyone question if I’m anchoring. Like another member said earlier, golf is a game of integrity.
