RGB imaging works well for bright targets but is slow to build SNR on dimmer ones.

I once read a claim, based on empirical evidence, that you should do equal amounts of L, R, G and B. I didn't find the argument completely convincing, but it's probably a reasonable place to start.

I reckon the optimal strategy varies depending on the target and what you're trying to emphasise in the object. If you're trying to bring out dim dusty stuff then you will want to go heavy on L. If you have a colourful galaxy then you'll need a decent swag of RGB.

Cheers,
Rick.
