I have a Benelli Nova 12 gauge. I already have a full choke tube, but want an extra full or super full turkey choke tube. In your experience, what brand and model choke tube delivers the densest and most uniformed pattern. I am looking at MAD Calls and Lotham. The tubes say they are for turkey, but I do not know that they will be any better than my full tube. As a note, I will be shooting Remington 3.5" #4 shot through the tube.
