Depends on what shell and how far your shooting. I have a 3" vinci with a 28" barrel and have my best results so far with a Sumtoy .650 choke shooting 3"
magblends.It also does well with federal turkey thug 3" in #5s and#6s. There are some super vinci shooters here, hopefully some can chime in with some suggestions for you. So far my experience with the small bore benellis is that generally speaking they like the tighter chokes in most brands, somewhere in the .650 to.660 range. The .665 kicks I tested in this gun started to open up pretty thin at 40 yards with lead. I have not tried either of the chokes you have mentioned, but they are both of high
quality.You can go to the pattern picture forum here and see what combos guys are shooting with the benellis. Hot ticket this year seems to be the new win longbeard shells,Guys are getting phenominal patterns with them for lead shells. Good luck, and
