I'm a bit old school. Still playing 1990 (legal groove) PING Eye 2 beryllium-coppers (1-SW). Best clubs money can't buy anymore. Believe Lumpy still plays the stainless Eye 2's, and Calc uses the beryllium wedges.
I always felt like they were a much softer feel than other cast clubs, especially when the balls started getting harder.
Still have a set of 1966 MacGregor MTs (black face) with original shafts. The heads are still in great shape, not sure why some of the newer forged clubs don't hold up so well. Had a set of '77 Staffs (didn't everybody?) where some of the chrome actually peeled off. Great sticks though--carried that PW with other sets.
