Super Vinci choke tube recommendations

[Skeeter41]

Any recommendations for a choke tube for a super vinci.  Planning on shooting 3 inch #9 Tss.  My 12 year old son will be shooting it so I don't want a super tight pattern.

Anyone shoot an Indian Creek .665?

My combination for Super Vinci was pretty simple and I had the 28" barrel.

Standard  Carlson's LBXR choke in 0.665". Shells were LBXR #5 IN 3.5" at 2oz of shot. I felt pretty comfortable out to about 55 yards with it.

Your son could go down to 3" #5 if he didn't like the recoil of the 3.5's.
