IMHO you do save wire and labor by going to the closest outlet with the HR. Also I like to try and wire in a way that I think would make the most sense to most electricians when troubleshooting. I do use multi-wire branch circuits when it makes sense to me but I am not real keen on using alot of them since I have seen too many that were not balanced on seperate legs. Breakers can get switched in the panel (to the same leg), after I'm done, by someone who does not know better. Also it seems like there is less possibility of power quality issues when running 2 wire home runs.
Any thoughts/comments on PQ with multi-wire branch circuits?
