Always glad to see tinkering and fun projects, and I don't actually hate the compass unit, and will still use one depending on what I'm doing.
That being said, I would recommend against running it too much with the "tritium mod" to make the compass "constant on," as you'll end up burning the shadow of the compass display into your tube--it's just like leaving an image paused on an analog television for too long, as long as the image is in motion, it's a non-issue, but even if it's at a "safe" level of illumination, it will eventually leave its mark on the analog tube.
This is the same reason some claim that the COTI can cause long term tube damage--if you leave the compass display constant on, or if you consistently run it too bright so that you have the illuminated field of view constantly for a long duration (ideally, you would reduce the gain of the COTI to where the "FOV" is not visible or barely visible most of time--it also adjusts brightness/gain automatically).
Beyond that, I actually like the USGI compass requiring a little force to activate versus activating too easily--I'm not necessarily using mine for dead-reckoning navigation when I'm using it, it's more of a quick general azimuth check, so a quick squeeze and read is all I need. That being said, some can definitely be a little stiff, especially when they're reaching the end of their life.
