[CQ-Contest] Coax Stubs for SO2R

Wondering how those of you using a Six Pack antenna switch hookup your stubs? I have two coax cables from the Six Pack coming into the shack going to each radio. Each station has a multi band Dunestar switchable filter. For the most part the Dunestar works well but since I recently added an KPA500 to my run station, when I'm on 40 meters with the amp it gets into 20 meters on station #2 pretty bad. Are you all using a T connector and have the stubs for each band on a manual multi position antenna switch?

Also does anyone know if the Dunestar's are tuned for a specific part of the band. On 80 meters mine seems to have a very high SWR when I switch it in even though the SWR on the KPA500 looks good.
