This is my first year with the ACC PRO Hunters...yes. However, other than the last two years using the FLATLINES, I have been using the ACC 3-49 since 2008 and LOVE THEM!!!! My only issue with the Pro Hunter thus far is the HP-2 insert (23 grains). I am going to play with some other ones if I can find the right diameters and cut the weight down a little. PS I haven't weighed them since I finished them.
Here is my reason for the 6. I am building these arrows for 1 hunt! My Kansas Mule Deer tag. I am going to be using my Vector Turbo and the chances are...since its Kansas...the wind will be blowing (so yes the 23 grain HP-2 insert will be helpful for FOC...I know). Using the AAE 2" shield cut vanes I get to cut down the total surface area and the higher profile of most 2" vanes and therefore reduce horizontal wind drag. I am using 6 instead of 3 or 4 for control and stability with my broadheads (I will be shooting an Ulmer EDGE and want plenty of control). I am also using 6 1.5" Fusions on my ACC 3-49s out for my Element for elk this year (same head). Kansas wind was the biggest factor and cutting down the profile of my vanes for better clearance.
Just converted my Vector Turbo over tonight from my 3D/Field set-up so I will hammering away with them this weekend.
