The vang is really nice for downwind sailing, keeping the boom from rising up enough to whack the backstay during that unintended gybe that will happen.
You could look into the fabrication/installation of a mast gate to retain your slugs, something I haven't done, nor plan to do on this boat. I do move to the mast when reefing to drop the slug stopper from just above the slug gate to just below the gate, then it's right back to the cockpit where everything else I need is led.
As for what works for the individual, that's a factor that also includes "where you sail". I don't know about your sailing grounds other than "Oregon lakes", but in the Sea of Cortez, besides the occasional winds, there are also waves and swells pitching your boat, making the trip to the mast that much more exciting.
The more you can do from the relative safety of the cockpit, the better, IMO.
