If I'm not in a hurry I go to the left so I don't feel like I have to monitor quick-cutters from two directions and it makes the whole drive easier. If I'm in a hurry I consider each lane like its own Slinky, expanding and contracting; my method is after my lane has a good run where I'm passing others, I switch to any other lane and hope to catch it in the right Slinky stage.

Seems to work better than sticking with a lane. Probably just the placebo effect, but I'll take it.
