I am trying them, Blazers, as we speak. Being a die hard feather fan, I am trying them because a Bohning rep gave me a couple of packs

Like above, I fletched mine starting at the same mark I always fletched my feathers. If you are like me, I get used to the fletching touching my face in the same place, which helps with head orientation (I don't use a peep). So, starting them at the same place on the arrow kept things the same.

On a side note, the Bitz was a great choice. I tried fletching the Blazers on a helical JoJan and they just would not get good contact. I could get them on there, but they weren't all that pretty and some wanted to come loose. I borrowed my buddy's Bitz with right helical clamp and they stick really good and make good contact for the length of the vane. No coming off now.
