It really shouldn't matter how you align them if your arrows are properly spined. I mount my Zwickey single blade Eskimos horizontally. They are "laying flat" as I aim. This way it doesn't interfere with my aiming, just my personal preference. I believe in a full helical on all my arrows too, both 5.5" and 5" feathers. I apply as much "wrap" as I can. This will help stabilize your arrow. Experiment with different alignments and see what works best for you. Good Luck...
