If you did not produce enough energy to blow the three blades through the ribs, then you likely dont have enough energy to ethically shoot the two blades either. The odds of the blades being lined up to slide between the ribs are very low. A good fixed blade head would serve you better. Any good head should easily blow through rib bones.
Because i have heard very good things about them and they are mechanical and i want to be able to not tune my bow much from the field point tune
If you need to make adjustments from field tips to broadheads then you're not tuned properly. My bow hits in the same spot whether I shoot a FP, Rage, or Muzzy.
