I am the lucky recipient of Mike's Z101s. I have to say that they are in excellent shape and Mike is an outstanding seller. I tried to post feedback, but the link just comes up with a (file does not exist). Anyway, I used the clubs today and I really like the feel. It could just be the honeymoon, but they are at leat a half club longer than my X16 pros. I flew a few greens and had to drop down a club on several shots. The vokeys are also excellent. These are the first Titleist clubs I have owned (except for a very brief time with a 983K) and I really like how they set up.

PS. Mike: I will try to post feedback later.
