I do. I think they're ridiculous and inherently unsafe. I won't dive them or dive with people who use them. Case closed.
And I'd rather be called a jerk or elitist or a-hole then have to deal with a dead/hurt buddy because of shoddy gear choices.
To assume that something is unsafe because it isn't good for caves IS elitist. You calling something shoddy to defend your position reinforces that elitist attitude. I didn't know that I had to make gear choices based on other peoples conclusions, right or wrong.
