4. Those bleeder blades give that much more cutting surface, and they're small enough to not hinder penetration enough to matter. Cutting surface is important, and more is normally better. And since the cutting diameter of a 2 and 4 blade stinger is the same......it's just no question in my book. And they fly absolutely straight. They're incredible.

Jeff, in the case of you shooting them w/ trad gear......I dunno. I don't have any experience with trad, so I'm not sure how the other blades could, or even would, hinder penetration at all. I doubt that they would enough to matter.

For easy math, let's say a deer is 10" wide. If you're shooting a broadhead w/ a 1" cutting diameter, and that head is a 2 blade, you're getting 10" of cutting surface. Now, let's take a4 blade Stinger. To that 10" cutting surface, we must add the two 1/4" bleeder blades. So add another 5" of cutting surface. You know have 15" of cut instead of 10.
