Now in my code, every time I come around in the main loop, I would
alternate the output between V1 and V3.  Bright LEDs would get set
all the time (both times), and dim LED's would get set only on alternate
cycles -- sort of like a pulse-width dimmer.

Seems OK, assuming that there is no even pattern in your main loop cycle
times. BTW an 872 has PWM hardware....
