What Combo?

[Punisher]

I just purchased a Remmy 870 Express 26" 20 ga.  I bought a Rhino .575 cheap off a friend and ran some lead shot through it.  I was actually pretty impressed.  I was wondering what choke some of you guys recommend.  I would like to stick with lead shot.  I thought about buying a Swarm, SSX, Rem. Super Full, or a Carlson's, or something else if someone thinks another choke would work better. Thanks.

Just saw the Fiocchi Golden Pheasant comes in 3"/1.25 oz./7 1/2.  I was wondering if anybody had tried these.  Again any help would be greatly appreciated.

I also just bought a 20ga express 26" barrel and i also would like like to know a shot/choke combo for this. I'm leading towards federal heavy weight 7's.
