^^^ Guaranteed choke plays a key role when comparing all things TSS. You can go as deep down the rabbit hole as you want when it compares to patterning and comparing, all at a cost. I patterned numerous 12G and 20G chokes back in the day with my handloads and have hunted with a $45 BPS 20G .575 choke (Made by Carlson) while my beloved Indian Creek .570 sits in my safe. I am an IC guy all the way, but it never sees the light of day with my current "20G hunting setup" where I am looking for more even 250/250 pellets counts at 40 yards, not a hot core 350 pellets in 10" circle. Every setup will shoot a little different than the exact setup next to it. The only way to know for sure is to burn shells, money and time to make a final determination. At the end of the day, we are splitting hairs. Find you a good 200-225 in the 10" and 20" and go hunting, and save yourself money and time. IMO, ensuring POA=POI is far more important than number of pellets. My .02
