Slick trick mag, and g5 striker.
Now that is with a perfectly tuned bow, sub 300 fps, heavy arrows with high foc (I don’t have the numbers on me right now), and spin testing every arrow/broadhead combination.
I posted a broadhead review on here a while back, check that out.

You are right that certain broadheads will not shoot well out of certain setups regardless of tune. Longer heads with fewer blades and smaller vents are the most finicky. I do NOT screw with my tuning to shoot a certain broadhead, that’s bass ackwards thinking. Nor do I ever practice with my hunting heads. I keep the ones that have been used in critters to practice with.
And I don’t shoot mechanicals because they all break, fail, or cause too much resistance to pass through.
