If anything, I'd re-wire them up so instead of 2s2p, they are 1s4p. And then use the 100-150 ohm resistor for each LED. You could use a single common resistor for all LEDs in parallel, but that's not advised.

You know -- the LEDs that are on-board the MMP are driven by the BEC ... and they are 3P with 470 ohms on each.
So sounds to me like Brian's idea would be best.
