RE: best vanes combo for fixed blade broadheads
I wasn't totally satisfied with Blazers and I experimented with using four vanes also. They dropped no more than ones with three vanes but they flew better. I thought that they were noisier but I found a solution that worked great, I moved twoopposing vanes 1" forward on the arrow so that the vanes were staggered. Blazers are tall vanes and I was having some clearance issues, I've since switched to 3.125" QuickSpins and they work great with broadheads. You can get good deals on them on E-bay.
