The DIR thing gets a lot of heat on some forums. We think any advanced training is good, and that includes GUE training.

The idea of knowing your tech gasses, kowing how to calculate your run times, turn around points, gas consumptions, RMV, etc are all beneficial. (ok, so I had to ask my tech friends that one, hehe)

One of the things we don't want do to is let a particular dive discipline have to constantly account for themselves, that is no fun, but balance that with the fact that every good idea can withstand muster.

We see DIR discussions between detractors and proponants get totally heated and personal on other boards. I am pleased that so far that hasn't happened in this thread, so you guys are to be commended in exercising restraint, as I can tell you're all trying!
