Your current setup should be a great choice. I wouldn't change a thing. Generally the only thing I would do differently would be to add a large cutting mech b-head just to inflict maximum damage and a huge cut. I have found that the added shock and trama seems to help put the birds down faster and make recoveries shorter. However, you certainly wouldn't have to change a thing to have a great turkey rig. Good luck and good shootin'
The Rocket Sledgehammer is simply awesome! A HUGE 3 1/2" cut will stone any bird that comes close enough!
