I did not use them for hunting season. When I tried them out it was to close to the opener to change anything on my hunting bow. I plan on playing around with them some more soon. Basicly I found them to be true to the advertising. They do add weight to your arrow, but the down range "drop" compared to the same arrow without the system is the same, and maybe a bit less. They save on serving wear, and do aid in accuracy with smaller fletching and broadheads. 3" fletches would control a broadhead where it took 4" with conventional nocks to do the same. I understand that a lot of people are using them for competion shooting. I think the system has a lot going for it, I am not sure how much the average hunter would benifit, but I really can't see any drawbacks and thier are a lot of positives. I will see if I can find the report I wrote and repost it for you.
