I have yet to shoot the Phantoms, but i have heard good things. I know though with that style of broadhead you tend to get more spin. A helical arrow will probably assist you in controling that spin. That style head is going to catch more air as it spins and the helical can actually help control it. The blazers in such work great on your standard MX3 and MX4s but i think with the Phantom you will get better results with a helical fletch in larger vanes, just my opinon from shooting that style of broadheads before. Nothing scientific behind it, just my past experience.
