Hi Bill, it doesn't matter what feather configuration you use unless you are using a single bevel configured broadhead as they spiral on penetration and you may aswell have the shaft spinning the way it is going to turn upon impact.Viewed this DVD and found that it took away from me a number of things that I believed to be correct, , the DVD presenter stated that a right hand archer needs to shoot arrows fletched with left hand helical. I always thought that the left hand helical would spin away the arrow from its true flight path for a right handed shooter . not so much the worry about the fletching hitting the arrow shelf. The setting up of the arrow on top of the nocking point instead of under. Under the nocking point, stops the arrow from sliding off. Dipping of an arrow without an overflow bowl. Just a couple of points to ponder for now.........Bill
2 nocking points are best as preferred by most top archers. Nocking the arrow above has it's merits in the fact that archers tend to force the arrow down on release. Nocking the arrow below has it's merits as it will prevent the shaft riding up the string when standing with the arrow on the string and will be better for speed shooting and 3 under type finger configurations.
Another point about feather fletch is that the shafts dont spin until leaving the bow so clearance should not be an issue. I recently recieved some arrows from Tommo that are fletched with left wing and I see now issue in arrow flight or clearance etc. Steve
