I got my regulators converted to DIN, the main reason being I want to start diving doubles soon-ish. Since I still have the yoke parts, I should (in theory) be able to swap it back for trips to the tropics but I'll most likely just use a spin-on adapter.
DIN is supposed to improve your trim and buoyancy control automagically, so I'm looking forward to that. On the other hand, it makes me look like I know what I'm doing, so ... um ... yeah.
