I would go with either the Jellyhead or the Tru Glo
Strut Stopper Xtreme, which isn't to be confused with the gobble stopper choke. You can order the SSX from the National Wild Turkey Federation website
www.nwtf.org. Either choke is a great choice and I have gotten similar patterns and results from both the Jellyhead and the SSX in my Rem 870 SPS-T with thumbhole. The SSX is about $35 where the Jellyhead is about $45.
