First things I would say:
1. If you go clockwise, you can only ever go round the outside loop. - Unless you reverse across the link.
2. If you go anti-clockwise, round the outside loop, you can enter the link from either top of bottom, but when you exit, you are then going clockwise. - See No.1
Of course this may not be a problem for you? But is quite limiting in 'play' value.
Assuming the link across is not metres-long? You will need a reverse loop module for the left-half of the outside loop.
* I think that will do it, but am prepared for the wrath of others, if I have it wrong!
