This is the 18 degree KZG H370 Tour and it seems to rock just a little bit open when you set it down. The 22 looks like it sits just a shade closed.
The Tour model is supposedly more compact than the H370 (which comes in a bunch of lofts), but it's not a tiny head.
I bought them with SK Fiber Hybrid Force shafts, they felt OK at the range yesterday, but the 18 is actually about 1/8" shorter than the 22, so I might reshaft them if the mood strikes. They feel very similar, so maybe they were part of a single length experiment. I have a dozen $1.50 Miyazakis from RBG that could get a tryout.
