in reply to bowfanatic: yes sir i am using the wb for carbon arrows.
my old arrows was some generic brand i think wolverine not sure dont remember and the ink is rubbed off from shooting. i am shooting gt xt 5575 at 28 inches with a 85 gr tip. (plan on shooting the 85 gr slick tricks) completed arrow weighs 356 grains per shipment order when i ordered them. i have them set with 4 blazer vane fletches, as i previously said they seamto shoot straight from the bow to the target.
bow is a bowtech bk2 set at 70 lbs and 30 inch draw.
to arroman my bow is really quiet and cams are correctly aligned with each other. all measurements show up as being correct.
