Why a SST on a double gun?

IMO, the best reason for a single trigger on a double, would be the pigeon ring. Other than that, why would anyone give up the advantage of the double trigger, instant choke selection.
I watched my hunting partner make a perfect dead in air double on a pair of incoming doves this morning, tight bbl first. It was poetry, and would have been difficult without double triggers.

Bill, you have a standing invitation. Just let me know we you want to make the journey way down south. John

Dennis, my Greener has a single trigger and was made in 1894. It was a gun Harry Greener kept 'in-house' as a platform for developing his various single trigger mechanisms. The gun was never proofed officially and was never retailed.
