I looked at the slick tricks on cabelas and read the reviews. I liked what i read and there were very few complaints that came from people that were shooting very fast bows. My bow is set at 65lbs. with a 28" draw. My arrow weighs right round 500 grains. I dont know for sure what the speed of my arrow is but i dont think it is fast enough to cause problems. The only other thing that concerned me is that they said the heads whistled or hissed in flight. Have you heard this? Do the deer seem to mind before they meet their maker? Sorry for all the questions but i will only be able to hunt for a month before i leave for basic training and i just found out that in my area of minnesota i can only take a buck. no antlerless permits will be given to anyone age 18 and over. I dont want to waste my time or my money on a head that will spook the dear or not work well when the time comes.
