Question about TSS and choke diameter.

[DMTJAGER]

If you were going buy a choke and planed on using Federal TSS turkey shells in #7 shot, are more open or tighter chokes a better choice? I have seen 12 gauge TSS specific chokes with ID's from .665 to .655, which will serve you better? All of my turkey barrels are either 24 or 26 inches in length.
