I think the fact that the first gun I owned was a double with 2 triggers given to me on my 12th birthday by my father has helped me. I never understood peoples problems with a 2 trigger gun....seems natural to me and I don't care for the single trigger. That said....its what works for you. I naturally pull the front trigger and slide to the rear after the shot during my remount. The idea of a single trigger on a double, no offense to either Westley or Mr. Sutherland(or you Will), is just....yuck! Too each thier own, but a single trigger is a deal killer for me.....I just couldn't live like that.
