Hevi shot, but they don't make them anymore. The HD's even patterns better than them. Each setup is different. HD's work better in mine. You may want to give them a try. They work great for me. I use the 3 1/2 6 shot.
Other than that my 870 super mag is not the SPS-T model, this is exactly what I have found with my gun. I have the identical choke you mentioned, Steve, and love the 3.5" #6's out of it. Killed one at 53 steps with that setup last year...stone cold. Normally wouldn't take a shot at that distance, but it was a limb-hanger and he was what we call hung up.
