Choke recommendation

[troutfisher13111]

I just bought a 20" barrel for my 20ga Rem 870 and have 5 boxes of 3" #7 Federal TSS on the way as well. Can someone recommend a good choke for a killing pattern from 20 to 40?

Seems like the consensus for those guns has been the either the IC or sumtoy in the 555-562 range
