That might be a teensy bit patronising?I thiink you took what I was saying in the wrong way, maybe misread it. I firmly in the camp that DIR / GUE can and should be able to dive however they like. I have also said that no one is forcing anyone to dive under DIR / GUE principals. My point was, I think there is a lot of sour grapes mentality from the divers that can't dive to DIR / GUE standards, for whatever reason.
The vast majority of divers have never heard of DIR, GUE and flat trim. Ask people.
For those who don't dive in flat trim (+finning, buoyancy, you know, decent core skills)... Either they don't know how to do it as they've never been shown decent skills with their recreational background. Or there's a bunch of people who just go diving and just don't care. Often the wreckies who bring lump hammers.
The number of people who do know about DIR and GUE generally admire their exemplary skills and dedication to hours in quarries practising. Some of those people simply reject some of the GUE/DIR principles, such as extreme team diving, reliance on the team not self, the rigid standardisation, and some arcane planning. There's no arrogance; it's just they don't see the point.
