Blazers vanes were designed to steer fix bladed broad heads. Having a higher profile in the back with less weight meant better weight forward tendencies. Personally, I would get a few arrows with Blazers on and compare them with what your shooting now. You may not like them. But if you do, then set the rest of then up!
I use them for everything, field tips and broad heads. Ill never go back to regular vanes again. Yes I do use them in right helical as well. Being so short, in a helical clamp, you can hardly tell there's a helical on it. The back of the vane has a slight keel on it. This gives me a bit more spin to stabilize that arrow a little bit faster. My vanes been on since 2008, and through a WB rest. No problems yet!
