Who disagrees with DIR and why?

My point was that this isn't a DIR-thing. It's a tech thing. DIR just said "hey if this works great for tech it will work great for rec". I think they are correct.

I used the same process as you for years. I'm still alive. I do think it is an okay process. Donating the primary on a long hose is just safer. Some dive shops teach donating primary in OW. I was taught both ways.

I'm basing your comfort level on statements like:

By giving away your primary you are giving up control, however temporary that may be for, you are still giving them control of you.

and

You are not doing your buddy any favors by being starved for air yourself. In a class I took this spring, a buddy and I had to swap our entire gear sets underwater While sharing a reg. It gets pretty intense waiting for that air to come back while at the same time performing a task or 2 to stablize their situation.

Those statements say to me that your comfort level with switching regs is an impediment to adopting the process. Sometimes words on a page convey the wrong message.
