I had a Hutchens and it worked but I thought it was uncomfortable. I bought my Hans a couple years ago and love it, its worth the money. I also got the Vision Advantage Plus tether and it makes a big fifference, no restriction when turning your head.
Also remember that the head and neck restraints do not help you in a side impact. You really need a good head and shoulder support sytem for your seat. Not the floppy braces that most people have, if you can move it with your hand its not going to work. It should have about 2" of high density foam on the head rest to be affective. We had a guy get a concusion when he barrel rolled and smacked his head on the roll cage because of his floppy head rests.
