Who disagrees with DIR and why?

[scubadog76]

I Don't think some of the config choices are the best either. The long octo is a great idea however I don't like the idea of giving away my primary and taking air from my octo. Given people have their equiptment in tip top shape, Octos still tend to be tuned a little lower to reduce freeflows and also not used nearly as much. I don't want to find that out the hard way and have a paniced buddy that won't give back your primary. It's their emergency, they should get the less certain air option. Also, I always tow a flag which to my understanding is not DIR. There are plenty of boaters that don't know what a dive flag is, but enough do. Put a safety sausage up there and every boater thinks it's something to salvage. I guess your not supposed to have a whistle either?> What do you use in it's place? I have not dug very deep into DIR practices, but these are things that do come to mind in what I have read.
