Well I must say I am very excited about the new 2 blade that RFA has brought to the table this year. It is an all steel broadhead with stainless steel blades, that has a cut that ranges from 1 1/16- 1 1/4" depending on the weight of the head.
The blades are used to change the heads weight so you can just order replacement blades to change head weight instead of new heads. I have been testing these heads for a couple months now and they flat out fly awesome. :thumbs_up
Here is a review done by Ike on them, in the video he does manage to break a proto type but the ferrule is now casehardened and a little more material was added to the weak spot to eliminate this issue.

They are also available to pre-order on the website. I put an order in for a couple packs to try, anyone else got a pre-order in? It says they will be shipping Oct 1, 2011.
