The owner at the shop just got back from ATA. He handed me a sample package of Bohning Blaser broadhead vanes. Supposedly, you stick these 2" vanes on at a 2 degree offset and they'll shoot any kind of broadhead you put on the arrow. All I can see different about them is they're stiff, even for a Bohning vane, thicker than normal and they've got a slightly different profile.

Anybody got the skinny on these before I waste my time doing up a couple arrows with 'em?
