The jig comes with 3 disc, 4 fletch 90 degree, 3 fletch 120 degree cock out, and 3 fletch 120 degree cock down. I use 3 fletches, so if they are set at 120 degrees, whats the difference between cock up and cock out? The cock out disc is what comes on the jig. I want my fletching to be oriented like the stock fletched Goldtips. I like to shoot cock up on my TKO and it doesn't matter where I put my cock for the Wisper Biscuit right???
