Eye to eye tails are used to create what tree climbing instructors call a "closed system", resulting in a finished friction hitch with both ends attached to the connector instead of one hanging loose, as with the traditional hitch or single-eye split tail. The eye-to-eye tail also allows use of several hitches that are easily learned and extremely smooth performing. By utilizing both ends of this type of split tail, friction is more evenly distributed, resulting in more consistent friction through a knot that is less binding, yet grabs quite firmly. The system is enhanced significantly when incorporating a Micro pulley that fair-leads the hitch for one handed slack tending.
