Posted this in the emoji thread then saw this thread, so copied and pasted it here a well.
One of the guys in our Quota Group has those in his bag. He has them in graphite and is about an 8 capper. Still uses a TM r7 driver. Both driver an irons were given to him by another member.
One of the best putters in our group and uses an old (~ 20 years) reject Bobby Grace. He worked at Bobby Grace's facility in St. Pete Fl. back then and got the head for free because the Bobby Grace signature was screwed up.
Anyway, he keeps saying he may get new equipment, but he's pretty cheap and I told him he may see some added forgiveness, but his scores most likely won't change.
He also carries his bag (everyone else either rides or uses a push cart) even in the Florida summer. And he's 68 years old.
