I'd go with comp-n-choke with I were only going to limit it to those two tubes. Just bought a Rhino tube and it's awesome out of my 870! you should comsider Rhino to add to you list. However, you might want to try the Jellyhead because I just heard from Sandy yesterday that Nitro is starting to work a load up for the Jellyhead .660 and the .665 tube. They're (Nitro) not sure just yet which one they like best but will have results in another month.

When does you season come in? I just sent out my Jellyhead and Kicks tube to another member in NY to try in his gun. If he's done testing them out soon I'll send them out to you to try.
