I love having a 3.5 kick the hell out of me!!
I tried some TSS, and they sucked out of my 12 and my sons 20. I’m sticking with 3.5 Longbeards in my 12 using a Rhino .660. My son’s 20 shoots the 3” longbeards with a Carlson choke great. Mine will reach out to around 65. His is deadly to at least 50.
Your chokes may have been too tight, TSS needs to "breath" a little to maximize the pattern.
