No particular preference, I'd just use what's easiest.
If you'd use the duty cycle, you have to "remember" what it was set
to until it's time to start the PWM again. The TRIS bit are just a
single bcf/bsf instruction. Faster and less code.

Sorry, I should have written "tie up a hole timer"...
I read "a second timer" in your text as a "hardware timer",
which isn't needed, as I wrote.
