ALong those same lines, toe out, or close to zero toe with loose steering components, will do some funky things. It has a mind of it's own. Each tire is fighting to be the one to steer.
Getting the dynamic toe closer to 0 helps lighten up the steering and make turning quicker, but the closer you get to zero toe going down the road the more flightly the car will feel. Good for racing and autoX (to a degree anyway), not so great for a street car or freeway stability. My stuff is all pretty new so I try to stay between 1/16" and 1/8" toe in, closer to 1/16" if I can. But I'm using toe plates not some fancy alignment rack so that's cutting it pretty fine.
