I think I know of which head you are talking about, but I have not tested them yet. I do have a vortex head to test. It has a 2" cut. I am also supposed to be getting some brand new vortex heads for testing, as soon as they are in production. I will see what I can do about getting a sample to test, but If I remember correctly I realy didn't like the way the blades opend on the sonoran heads.
