My go to reference for fly tying is The Fly Tyer’s Benchside Reference by Ted Leeson and Jim Schollmeyer
Here are some of their tips on various types of hollow hair and their uses
Use for spinning/stacking Most buoyant of all hollow hairs; flares easily but brittle and easily cut with thread
Spinning smaller bodies; small upright Good texture for smaller bodies and wings and caddis wings if tips are intact
Primarily tails, especially on larger flies Very fine, almost solid, but long
Extended bodies Coarse, but only moderate flare; broken tips common
Tails; upright and downwings Stiff; flares to about 45 degrees; short and best suited to small flies; spins poorly
Tails; wings on stoneflies and larger caddis Flares to about 45 degrees; longer than hock for larger flies; spins poorly
Caddis wings; spinning/stacking Produces more fully flared caddis wings; spins well for larger bodies
Comparaduns, Humpies, some spinning Uniform diameter fibers, short tip; moderately long but good for small flies
Tails Very hard, almost solid; winging material for tyers who prefer no flare; can be curved
Spinning/stacking Flares well; very long and best suited to larger flies
Tails; streamer downwings; upright wings Hair on upper 3/4 of tail virtually solid, no flare – best for wings. Hair near base of tail is
Short, fine Tails; upright and downwings on smaller flies; small Muddler heads
Tails; wings on larger flies Stiff; moderately coarse; little flare
Tails; quill-type bodies Coarse, virtually no flare
At Camp Rohrbach, most fly tying is done at my steering wheel tying bench or…
...outdoors where the slightest breeze will send your Jungle Cock feather to the next county.
Carrying a few simple items will prevent your tying session from turning into an exercise program.
Clip clothes pin will secure that Peacock eye.
Small glass jelly jars will protect hooks, dubbing and tied flies from the elements.
Use your windshield wipers to dry freshly lacquered plumage etc
Point to remember
These tips will keep your flies and materials out of the campfire
