I have recently purchased a Mathews Switchback and have installed a whisker biscuit on it. I am not 100% sure about fletching orientation. I am shooting it with the cock feather up right now. I am getting funny wearing on one fletching and have torn a couple of fletchings right off. Always the same fletching is wearing funny and being torn. I have only started to shoot the bow [ 50 shots about ] I am also getting a small bit of tail wagging in my arrows, I dont really know the proper term for this but I think someone will know what I mean. I am pretty new to the sport so any info would be really appreciated.
