The choke you need will depend on what load you choose to shoot -- Ive used the JH with good results on several loads -- there are some other very good quality chokes out there like PG etc.. - take a look in the 10 ga section for good pointers --
try some of the Federal HW #7's------ they are very good shells
Clark is right , the 10 gauge is dwindling more and more each year with turkey hunting , the 10 has been neglected , while the popularity of the 3.5 12's grows -- However I do notice that there is a small stronghold of popularity of the 10 with goose hunters , I dont think that will ever die off
