If you're used to DT's, there's absolutely no issue going from front to back. The easy way to learn is, shoot skeet. Since the advantage on skeet doubles is tight choke first/open second, you simply go back to front. Do it enough times and it becomes automatic. In sporting clays, on a particular station, you get the same presentation each time. Which means you always use the chokes in the same order. Look at the targets, determine whether you need to go tight barrel first, and follow the same sequence every time. It's about as difficult as walking and chewing bubblegum simultaneously.
Trigger spacing is also very different from one DT gun to the next. Admittedly, some are impossible to use in cold weather if you're wearing much of a glove. Others will accommodate a relatively heavy glove. Or, you can solve the problem by having a ST gun for cold weather hunting. I have some of each. And I don't have any problem, when shooting either skeet or sporting clays, remembering either to go back to front, or to switch the selector on the ST gun.
