OK, I knew I was going to have to deal with this problem sooner or later, but I never did in the past, so Im not sure what to do. I got a new switchback a while back, and have been shooting it every day, hitting perfectly with the field points. Finally today I decided to try the broadheads, and they are flying terrible! At 20 yards they can be up to 5-6" off! most commonly low and to the right. The fletching doesn't follow a straight path at all, I can't tell if it is tail whip, it looks like the whole arrow takes a spiraled path.

Do I have to make an adjustment to my arrow rest? Or is there more to it?

I am shooting CX hunter 300's and muzzy 100gr. 3 blade broadheads. I also shoot a NAP drop away rest. (the one with the solid arm that glides on the cables.)

ANy info would be great! THanks!
