I'm 6'4" 220# with fairly broad shoulders and dive with a backplate, so guessing the rings are negligible on me.
Maybe a dumb question with the pee valve, but if I go unbalanced can I just close it off and remove the hose when I'm not using it? A lot of my diving would be from my boat that has a nice head and I doubt I would use it 90% of the time, but I can see where they are nice on a half-day charter.
Yeah, pretty much what

The Trigon is awesome.
Get a set of these QD fittings (at least 2 of each - they're cheap and spares can be very handy):

Notice the female side is a dry break (AKA "with Shut-Off").
If you're not hooking up to your junk, just let the tube from the pee valve run up one leg, loop over and down into the other side.
With a Trigon, there is nothing on the valve to turn on or off. When you're hooked up to it, you just let 'er rip. If you're not hooked up to it, then it's fine. If the mushroom valve in the Trigon were to fail, it would let water in through the hose and into your suit.
That is where the female QD with dry break comes in. In that case, if you're not hooked up to it, water that came past a failed mushroom valve would be stopped by the female QD, so you still stay dry.
And if you are hooked up, then the worst that could happen is flooding your condom catheter. But, in reality, the air trapped in the line would actually prevent that.
I dive off boats on our local lakes. I could pee while on the boat, without using a pee valve. But, I would generally be planning to do more than one dive. Having to doff most of my drysuit so that I can pee in between dives is a royal pain. If I were only doing one dive for the day, then sure. MAYBE I wouldn't hook up my pee valve. But, if I'm doing 2 dives (or more), then I KNOW I will need to pee some time between when I first suit up and when I finish diving for the day - and that doff/don just to pee is way too much trouble. And if YOU don't need to pee at some point during a 2 dive day, you are not drinking enough water.
