I havent shot one yet. I would like to see a good report on it also to find out what the nock travel is.Find out if they solved a problem by going in a different direction, or just designed it because they could.It looks interesting, but complicated.I know I wouldnt be smart enough to change out the string and harness, without the engineer leaning over my shoulder. Those top idlers going in different directions would be handy. You could sharpen them up and trim branches for shooting lanes. Save a pound of weight in your daypack from not carrying a tree saw.
