Just to throw my 2p in. I use PCB wizard and I only used the auto routing once. I had 12 wire links and most of them spanned either the width or the length of the board. It seems universal that the autoroute facility is 'pants'. I did the board by hand and ended up with 4 links all 8mm long...... The PCB was a whole lot smaller and better laid out to :-D
Do it by hand whatever software you use!
