Removing a primary SMB from your left pocket and deploying it with one hand whilst keeping your finger on the trigger of a scooter on a 21m deco stop - now that I'd like to see!
Being facetious aside, most people on here have no wish to be awkward or begin to develop their own 'modified' version of DIR, but... unless people fully understand the detailed thinking behind the changes, to the point that they can see that the benefits of the change outweigh any problems (perceived or real) they may have with it, it is very difficult for thinking divers to accept the closed post from GUE and adopt the practices blindly.
If someone can't answer the question 'why do you do it that way?' to the curious diver approaching them at a dive site, and simply says 'because someone told me it's what I should do' without having an bulletproof answer, it makes us look exactly like the DIR stereotype of someone who follows a set of rules blindly because the angels came down from on high, spoke the word, and verily, it was so.
It may seem annoying that all these questions are asked when it has already been debated at length in instructor meetings, but hey - WE WEREN'T THERE! We need the GUE instructors to answer the questions generated by our debates so that we can see why these changes have been adopted. We need to feel happy that putting up with some (perceived or real) minor annoyances is worth it because it improves the system as a whole, and it's the integrity of the whole system that's the important thing. At the moment I'm guessing a lot of people aren't feeling that happiness.
