I would definately shoot mechanicals. Rocket makes a good broadhead that you can get with a 2" cutting diameter. I also like to bend a fish hook and screw it onto the end of the arrow so the arrow won' t penetrate. You want the arrow to stay in the turkey if possible. This really jars them when you hit em and many times if you make a bad shot you can run out and step on their head before they get away. Be very careful if you shoot one and the arrow is sticking out of the bird. I had a buddy that got cut by his own broadhead while tackling the bird. I really had to laugh, but now while he was looking. Ha ha!
