RE: Bohning blazer vanes
I tested Blazers for the local archery shop when they first came out. I was using ACC's to make sure I had decent arrows. The Blazers did fine with everything from 75 grains up to 100 gn T'Heads, Muzzy's, Bear Razorhead Lite and Steelforce. I started losing some accuracy when I got to larger diameter 125 grainers, like 6" groups at 30 yards instead of 3". Blazers could not control the big, unvented heads like Magnus I and Zwickey Delta though.
My results were with 33" arrows. Might have had different results with shorter arrows, but I didn't want to mount an overdraw on my bow just to test vanes. I also did not test them on large diameter aluminum arrows. I went into the test expecting a disaster and came away impressed at how well they actually performed with those particular arrows, within that particular range of broadhead sizes and weights. They do have their limits though.
