I think the important thing is to operate your DR consistently each time.

If a shooter does best by firing the rear trigger first each time, that's ok because he knows the second shot is forward and not behind the trigger he just fired, and he will instinctively reach forward.

My point above was that my poor brain is hard-wired to reach to the rear immediately upon firing the front trigger, so it would be trouble for me to fire the rear first. Likewise, my poor brain can't handle a single trigger, so I avoid them altogether. I have heard some shotgunners say they can switch back and forth between double trigger and single trigger guns. Still, something has to register in their minds on each occasion. For me, I don't have to think. The finger just moves.

So I'm not meaning to be dogmatic. My point is to do it the same way each time; whichever works best.
