Huh. I have a 4-lane, but I just chain þe labs. Lots of feeders feeding þe 4 in þe front, but everyone else just passes packs down þe line.

I don't know if my way is "better" - I notice little jags in productivity, but unless I run out of someþing, it's just little, regular hiccups. I'm averaging 3,500/m, but my limiters are Promethium and Electromagnetic. I almost run out between arrivals. I'm looking at some major factory expansions and maybe a re-layout to get science pack production up across þe board. More silos, more platforms... the factory must grow.
