There’s a mental fortitude required to sit down and whip out a couple dozen flies, knowing that too many won’t return to my fly box.
My attrition rate for dry flies is much lower than that of sub-surface flies. Dry flies have an affinity for shrubbery and tree branches but nymphing necessitates aggressiveness. As the adage goes, “If you’re not snagging bottom every once and a while, you’re not fishing deep enough.” Striking at any and all tics and twitches guarantees a strong hook-set in every stick and rock.
Depending on the stream or river, losing at least three flies a day can be expected. But this loss of sub-surface flies – and the hooking of more fish – is the only proof you’re getting nymphs deep enough.
There’s no proof that I’m saving much money tying my own flies. Materials aren’t too expensive, and except for thread and hooks, most of my materials were given to me from other fly tiers, either excess materials or those no longer used because they’ve moved on to something better. But recovery of the initial investment in a vise and the cost of hooks would require I fish more often.
It could be worse. Innumerable blogs and articles will tell you of the advantages to tying flies rather than buying them. Building durability into flies is cited as one big benefit, all it takes is more head cement (more dollars). One suggests using Kevlar thread (more dollars). Or better hooks (more dollars).
The biggest benefit to tying my own flies is the ability to create or duplicate any pattern, specifically those not available in the fly shops near home or on the road. It’s a good guess that all fly tiers have created their own variation of traditional patterns; one of mine is my “confidence” nymphs, a Red-Butt Zebra Midge. A simple pattern inspired by other, more complex, patterns more commonly used in lakes in British Columbia. But it’s often deadly on many streams on the east and west slopes of the central Sierra Nevada.
My flies won’t win a beauty contest, but it’s only the trout’s opinion that matters.
