I went to The Archery Shop yesterday to shoot my Slammer with a new LRU string built by Allen and shot 5 or 6 different arrows out of it. The one arrow that was head and shoulders above the rest in consistency of flight and accuracy was a Beman Matrix 460. The only problem with it is that at full draw the back of the point is right at the knuckle on my index finger of my bow hand.
So, I've had Budro order a dozen XX75 Camo 2213 arrows for me with bright fletching and bright nocks. The 2213 has a spine of .460 just like the Beman Matrix arrow I was shooting. I'm going to start with the arrows cut to 30", opposed to the 28" for the Beman Matrix, and adjust from there. I might add that Allen builds a very nice string, IMHO!
