for the simple slow stuff I'll be doing autorouting won't be a problem. I generally do "interactive auto routing", i will position my main parts as they need positioning and lay down any large power tracks, then let the autorouter have its way, then I look at the way it has routed and see if I can optimise my parts placement, i do any part move arounds and rerun the autorouter, I'll keep doing that until I'm happy, make a 5 hour job a 30 minute one.
