All broadheads work the same way . . . the cut on contact as they pass through (enter). So over the years, I have tried different BH's for different reasons. NAP Thunderheads, NAP Crossfires, Magnus Stinger 2-blade, and even tried some NAP Spitfire mechanicals for a couple seasons.
They will all do the job. But what is the one complaint that all archers have about BH's? They don't hit the target where the field points hit! (For the purpose of making my point . . .) So you had to retune your bow every season.
That is . . . until I started using the Slick Tricks BH's. Absolutely unbelieveable.
I went with the 100gr Magnum (1 1/8" cut). You can get them in 125gr also. The Spitfire flew like the field points, but you have that whole mechanical thing especially with large thick skinned critters like elk.
Try the Slick Tricks, you will never go back!
