Eclipse broadheads are well respected.
When pursueing turkeys, for me, a set-up that produces quick immobilization on less than perfect hits is key to routinely harvest birds.
My suggestion and what I live by, is to go with the largest BH possible that will tune with your set-up and still impart excellent penetration.
Any BH put in the right place will down a bird quickly. The small dixie cup size target is moving, can reverse on a dime, unpredictable and sometimes hidden by the turkeys different postures then coupled with my own adrenaline and sometimes inept skills & adrenaline requires further scrutiny of my set-up. My intention is to significantly increase the odds.
Turkeys should not be underestimated.
