I've kind of gotten over the aversion to noise in lux renders. I don't want it to be too noticeable, but there's still a certain amount of noise and grain in real cameras too.  It's just the way things are lighted sometimes.  Although, I noticed that I get faster renders and less noise when using Callad's mesh light.   Here's one I did recently using Callad's light mesh and trying out the LAMH plugin:  

The 500,000 strand fur created an 850meg .ply for lux.  hehe  Nice for stills, but it'd be a pain to try and get it rigged properly for animation.
