JDW - granted that some people don't seem to have whatever learning mechanism works for two triggers. However, I never think of which trigger I'll pull. I simply decide on the best order, open - tight or tight - open, and the trigger selection happens on autopilot. I am no more able to explain how that happens for me than why it does not happen for everyone. But, for some/many it does happen that way. Single triggers were invented for those for whom it does not happen.
