True, but Specctra keeps its sticky hands off my carefully hand-routed 
analogue sections, and routes the huge amounts of digital logic perfectly 
adequately. Sure, I _could_ do better, but not in a sane amount of time...
I'm not sure that Specctra cares about, or has been tuned for, single-sided 
boards - it certainly seems happiest when faced with a board with power 
planes, when the results with a decent .do file are acceptable. I never got it to 
deliver a decent power / ground grid. Fortunately, I no longer care... (And, for 
smaller boards, the Protel autorouter often works better, but hand-routing still 
wins if I need something better than a prototype hack.)
