What are you shooting on the tips? If your using fixed braodaheads, I'd go with a five inch, if you are going mechanicals, then a four inch should be fine. I'd use the Easton Vanes it using the four inch or AAE elites if using the 5 inch. Easton stopped making 5 inch for some reason. Some people say that the they are the same exact vanres, and I believe thatm however, I always seems to have better luck applying glue to the eastons.
