I recently tried out the Bohning Helix. Jig made for putting a 3 degree helical on the 2" blazer. Before I used the Bitzenberger with approx. 1 degree offset. With the 3 degree: 60 yard pin on target-arrow in the dirt. I'm wondering if this is just too much helical on such a short vane. Seems to have slowed my arrow considerably. My friend also said my arrow was very noisy. I shot my arrows with 1 degree offset and was happier with performance. The jig was easier to use than the Bitzenberger, but just not too sure about that much offset.
