I played the Zings for a few years, bought a set for like $250.... they were in great shape, didn't even have to replace the grips on them when they arrived. This was back near the early 2000's.
That's still a very good deal.
A buddy of mine still games them, he also has the set LW. He shoots 75 and bitches about how many putts he missed from close range. LOL
So they're still popular irons within certain circles. He hits 'em great. I'd never tell him to try something newer.
