You will find that proper toein and caster are more important on a tail dragger. If you do not have some toein--and equal amounts on both wheels--ground loops are more apt to happen. Also, placement of the main landing gear relative to the CG is more important on a tail dragger. If you get the gear to far ahead of the CG, landings will be very bouncy and takeoffs requiring more runway before lift off, if to far aft, you will tend to nose over when taxiing.
