I shoot an 870. I'm going with a Rhino choke tube next spring. I've used Charles Daly, Untertaker and Remington Turkey XXFull. Best pattern I got was the Remington Turkey choke w/ Nitro loads. I love using the Nitro or Winchester Supreme - lots of guys like the Hevishot tho. Personally, I haven't tried it yet - maybe this spring though!
