Just wondering what everyone prefers between the two blazers. I shoot 2 inch quickspins but it seems like the 1.5" quickspins are creating a bit of a stir. What ya think?

1.5" for me, love them!

2 inch blazers!

1.5" Blazers are not recommended for hunting. They were designed for field tip use and may not provide enough stability for a broadhead. I believe that it says that on Bohning's site.
From the site:

A two inch vane great for use with fixed blade or mechanical broadheads. Helps eliminate interference problems and increases speed.

1.5" version of our Blazer vane, designed specifically for target shooters looking for the Blazer's steering capabilities, with less weight. Weighs 4 grains, .4 inches high.

well there it is. Thanks. Question is answered.
