I've had Zing 2's for 11 years, and love them
I bought mine in 1994, blue dot, jz shafts +3/4", 2-sw. They have been great, wonderful feel, very forgiving, no complaints.
Well, one complaint actually, but not the fault of the clubs. I am 6'5" tall, and just for grins got refit. They tell me I actually need +1-1/2", so I am taking the opportunity to upgrade to Ping G2's.
Let me know if you're interested in my Zing 2's. I plan to put them on Ebay in a couple of weeks.
