Been there with my old XG-M, that shutter freeze is a real pain.

What about a warm, toasted brown instead?

That mask strap story is a real wake-up call. Read a diving magazine article last year that said mask failures are way more common than people assume. They recommended doing a quick strap check as part of your pre-dive routine, looking for any dry rot or cracks. A guy in the article had his snap just from the pressure change during a simple descent, no contact with anything. Makes you realize how a tiny piece of gear can cause such a big problem.
