Franchi affinity choke recommendations

[strum]

My buddy just got the Affinity 3.5 turkey.  we tried the Carlson's with 3" federal tss 9s. its ok but i know it can do better.  Indian creek .665 is my choice. Or a Sumtoy.. he wants tight as possible out to 40 ish. going  to stick with 3" tss

any thoughts? thanks guys
