Where SSTs really show out is on a Sporting Clays course, where you get to view the presentation first, select which barrel/choke you desire to fire first, and quit thinking about it. Saves changing choke tubes a whole lot of times. With double triggers, I can guarantee you will pull either the front or rear trigger in the wrong sequence on a five pair station. Might not matter to a casual shooter, but in competition, it matters a lot.

Well said, John. I agree with you, even if I do not do so in practice. I compete in S x S events with a non-selectable BSS, choked mod. and full. When I compete in the main events and prelims it is with a fixed choke non-selectable MX-8 choked .020" and .020". I will, more than likely, have the chokes on the BSS opened to the same mod/mod set-up, even though the mod/full worked pretty well at the U.S. Open. I have found a great freedom in approaching competition knowing I have enough choke for any presentation out there, and not being bothered with changing chokes all the time. The concern that my patterns would be too tight for rabbits and close-in crossers just has not materialized into a loss of birds in reality.
But, for most people, the SST set-up, for the exact reasons you stated, is tops.
