Toe out will cause your plane to "dart" left or right (from experience). If you have problems during roll out then check your toe in.
A little toe in is good as when your legs flex back and out (when you hit little bumps and/or apply the brakes) they will cause toe out. (because the wheel is mounted on the outside of the leg and therefore must cause rotational flexing backwards, thus toe out) Also, when doing your wheel alignment think about where you need your handling to be it's best (talking tail dragger here as my tricycle experience very limited). I need it most when the rudder is becoming least effective. When doing a wheel landing, tail up, there is minimal weight on the undercarriage as the wings are taking most of the load and the rudder is responsive. The problems for me occur as the tail comes down and the rudder looses effectiveness. Toe out made me swerve all over the runway. When doing a 3 point landing, we KR2 pilots lift the tail wheel and then I have the same problems as above. If I do a 3 pointer and keep the tail on the ground (rare but possible) I don't have a problem as the tail wheel is steering, though I can feel it wanting to "dart" but it is manageable. After talking with a guy who restores war birds, mostly tail draggers, he recommended doing the wheel alignment with the tail on the ground with average landing weight and giving it a slight toe in. Also most of our time on the ground is with the tail down (taxiing, etc) and this gives best (minimum) wear on the tires. After taking his advice my bird became much better on the ground. Originally I did my wheel alignment in the flying attitude, wheel up, with no toe in, as I put my tail wheel on the ground I got toe out.

Of course the more toe in, the more wear on your tires. My understanding is that the toe-in helps you maintain a straight run as when one wheel starts to turn from toe in, to straight, the other puts on more drag by toeing in more, helping pull the plane back to straight.
