I got a set of Mizuno QUAD irons (3-pw) that are hollow, with Mizuno graphite shafts (flex 8 whatever flex that means.. -Feels like Dynamic gold regular)

-anyway, I tried to find them in your database, but was out of luck.


On the ferule it says 8601A8 -and I know that these irons were made from 86-88, so I guess these are from 86.

My question is, if anyone have any specs for these irons?


Anything, like lofts MOI and maybe old ads?  or even MPF data?


They feel a little light (swingweights are D0), compared to what I am used to, but they are really nice, and they look amazing, even compared to the newer hollow irons out there.


Thanks in advance :-)
