The most foolproof and effective way is to switch as often as you get the chance.
Every time you have a hand free for that, just switch without checking pressure or time.
With that method you just look at your spgs occasionally to check for stupidity, but have the tanks more or less equalized all the time without checking constantly.
Also use everything that happens during the dive as a reminder:
Reached bubble check depth - switch.
Reached bottom - switch
Reach an object - switch
Leave an object behind - switch
Cavedivers often recommend it this way with cavediver specific signals:
at every T - switch
at every turn -switch
Things like that...
You can also learn to identify the tanks behavior when close to empty as a warning sign and learn to guess remaining pressure close enough to do without spgs in a pitch.
