hi 1Cam.
Its advantageous to attatch a dropper tag for the second fly 20 inches above the lead fly. This distance between flies should be held regardless of the length of tippet to the sighter which may be determined by river conditions and depth. In Aaron's DVD he goes over in exacting detail everything you need including a very descript tutorial on all the knots required for leader construction. For example, the dropper can be lighter than the lead fly enabling it to saunter along in the current at a little higher position in the water column. Heres one for you from grampa Jasper. Aaron quotes him often. "If tippet was meant to be tied off the bend of a hook they surely would have put an eye there."![]()
