So RG, your thoughts please: I feel like I've heard this movie before.

Spiffy new device comes out, engineered technology thing from Europe that nobody's heard of, highly endorsed by RG as the better way to go, works well, addresses some safety issues, and locks down even for double ropes.

I'm not saying the TRE wasn't neat, but ....

Why not just stick with thicker ropes and familiar belay devices?
