Every year I get tired of shooting the same field tips at the same target over and over and over again. So last year I started shooting my 75 Grain Rocket Wolverines into water jugs, ply wood, fruit, foam insulation board, stacked card board, shaken up beer cans, what ever I could find to hold my interest for a while. But I couldn' t find many 75 Grain Broadheads to shoot. This year I am switching to the 100 grain tips. I wanted to get your opinion on what you thougt were the top 3 100 Grain Mechanical heads. I want to buy a pack of each and shoot the crap out of them this summer to see which one does the most damage and holds up the best. I was thinking of: Rocket Sidewinders, Rocky Mountain Snypers, and NAP Spitfires.
