Hackletip:

I suppose the pattern and it's attributes depend as much on the species and size, as well as how you intend to fish it, as anything else.

Where I fish in the Eastern US, our cranes are dainty and smallish (<#12)..typicaly yellow or orange. Body color is important--so is the "dainty" aspect.

A small soft hackle works wonders but many folks prefer dry flies.

As far as the dubbing: Tups is the fur from a Ram's scrotum. If you go collecting, please grab me some too . I have good success with imitative dubbing from bunnies, and even synthetics like Fly-Rite. But the Tups Indispensible is a good pattern no matter which substitute dubbing you use.
