Loonook,
I went ahead and used the following picture you recommended (alternating single and double wide passages to enable combat):
It was a good compromise between the nice looking circular ones with curved paths, and what I could actually reproduce on a battle grid as the players explored. I added some traps, some umber hulks and gelatinous cubes and let the players loose!
Here's the adventure log for anyone running a similar labyrinth.
Aeon Zen | Taurus Labyrinth | Obsidian Portal
One thing I noticed is that having a single path probably reduced gaming time considerably, since I didn't have to constantly ask my players which path to take. They were more entertained with the combat and the traps than having to map out a maze.
