Micha....
I'm in agreement with your priority list. Also, while I didn't like the delayed dealer bj in the beginning, I do now. I have found ways to use it to my advantage in tournament play and would hate to give it up now. This is of course with the ace showing. It would save no time (it may actually take longer) to expose the bj with the ace up. I vote to leave it as is.
And thank you for your interest.
