I've more than enough equipment for myself and maybe another person or maybe even two to hit the water.
But I'm not a guide.
In the past I could anticipate using more of a certain build and fewer of some, but time has passed and I don't intend to build stock.
I do like to have at least two different rigs setup and ready to cast when I go. One for surface and the other for another surface or a deeper water setup. Maybe one with an ant and the other with an Adams, maybe a cranefly, but surface and deep setups ready to cast.
I still have the remnants of a 6' Silaflex 6wt that I beat like hell on small streams in high school. The top guide is heavily grooved from flyline cutting into it. Guides broke and were replaced. The rod broke just at the top of the ferrule and was repaired to keep it as a good beater rod.
Of the 10+ flyrods and at least a half dozen working fly reels that I still have and consider good, I have tested and labeled each one after determining certain characteristics and appropriateness for certain waters, techniques, casting distances, line weights, and, for some, the fly types.
A late friend of mine who was a long-time guide, had inherited his brother's rod and reel collection. His brother was not a guide but was heavy into flyfishing and maintained a good collection in order to be prepared for every opportunity. From the Bahamas to the Beaverkill, etc. And as is best for actually being prepared, he was a bit of a perfectionist with organizing.
My friend owned many flyrods over the years, but used everything hard. He used his equipment heavily with many clients and most days was on the water and at the vise.
Their father was a dedicated fly fisherman and fly tyer and had a good collection of fly rods, but also spinning and baitcasting.
(His father was best friends with George Harvey and after they died a lot of fly tying material and rods and other fishing equipment stuff ended up going to my friend. Then when my friend died it was recycled into the flyfishing world!)
When my friend had inherited the rods and reels, he said that each one of his brother's rods were already set up to hit the water. Reels, lines, leaders and tippets and ready to roll. Sizes from saltwater to tiny water.
My friend said that after he got those rods he had a total of 125 complete flyrod setups.
As a guide my friend usually had 25 rigs all set up and ready. Others he had for other excursions.
But he was all-in for flyfishing and guiding and he inherited some of the best equipment and materials anyone would want.
He was able to sell some of the rods that he would never use. But it was amazing for a while to know someone who had 125 fully ready to roll flyrods!
And now, to switch to the fly tying discussion part of this post, as far as tying, I also have a Thompson vise. It wasn't the first vise. It was my first nice vise. I like the cast iron post and the red spinning tightener.
Still good to use. Match the vise to the hook and the fly.
