I'm a feathers guy myself but I am currently using some blazers on 2213's that weigh around 450 grns. I am pretty impressed with them.

I have tried a lot of different fletchings and if I felt I had to use vanes there is no doubt I would go with the blazers and a slight offset.

The only down side to them is they are pretty stiff so they are not very forgiving at all of contact issues. They do have a smaller profile though. Other than that I can't think of a bad thing to say about them. They stabilize my arrows as well as 5 inch tru flight feathers do with the same amount of offset.
