I am pulling back 55 pounds with a 27 inch draw and am shooting around 225 fps. Since i have a slower bow would it make more sense to use a cut on contact broadhead. I just want to make sure i can get a clean and humane kill. Last year i shot a deer with a crimson talon and it only want half way through. Luckily i got the deer, but i just don't want that to happen again. I did get some slick tricks, but i'm not sure that would help the penetration problem. What our your thoughts???
