I'm sure other 835 shooters will chime in but I love the 7's. I shoot the older 7's (300325 and 300525) though a .670 Pure Gold and get 300+ in 10 at 40 with them. The 835 does really well with chokes in the .670-.676 range. The IC, Sumtoy, SSX and Stardot are a few that shoot the Hevi's and Longbeards very well. I haven't shot TSS though my 835 but the 7's dropped a South Dakota bird last May at 38 yards and the bird never moved when I pulled the trigger. When my 7's are gone, I have a supply of Longbeard 6's to go in the pipe. Good luck with whatever you decide to do.
