Since learning how secure the double fisherman's hitch in all of it's itterations is I've almost forgotten how to tie about 7-8 hitches/knots.

As long as you Tie/Dress/Set the Scaffold Hitch you can't go wrong. In this application it is so much more compact than any other termination.

In addition, a SH will trap your biner from spinning and possibly cross loading. Looking down and seeing a biner loaded across the gate is pretty scary! With loop terminations a cross load is much more likely than using a cinch-type termination.
