This past friday, the shop was slow, (I work part time in a Mathews dealership)so me and another friend realy put the Drenalin through the tests. I was inpressed with its speed, At 71 pounds with a 404 grain arrow and 30" draw it was spitting it out at 301-302 f/s, time and time again. I didn't have a lighter arrow in the store, and didn't want to make one just for this test. Up till this year in Idaho, to be legal our arrowshad tobe 400 grains or more. This year that law is now changed to 300 grains or more manly for the out of staters comming in to hunt. Around herenot many archers are switching over becasue a heavy arrow is surenice for elk, it gives you plenty of KE which is needed for them. Anyway I too will soon have aDrenalin come this spring.
