An "out of the box" idea... Look into Tenkara.
A realtor friend told me she had given up on fly fishing 'cause even after several lessons, she couldn't cast properly. I told her I could teach her to fly cast in 5 minutes. She came by, I took her out to the lawn and demonstrated the Tenkara technique. It took her THREE minutes to start casting accurately.

Maybe Gamakatsu? Found one online shop featuring Octopus hooks. Large. They have 2 in stock at $4.95 ea.🤔

Thanks beadling9... I'll keep looking.

Thank you for the reply. I went to the FISHUSA site. Bought some green tippet material, but a search for GREEN HOOKS got no hits. What did I do wrong, please?

Interesting... Are the hooks painted or is there a hook manufacturing company that makes green hooks?

It appears that trout and other species have difficulty seeing green. Some manufacturers make green-ish leader material to take advantage of this.
But we fly fishermen take pains to tie careful replicas of surface and sub-surface bugs... and then tie them on BLACK hooks!
Has anyone tried painting their fly hooks green?

I caught my first trout (on a worm!) in 1945 on a small stream in CA. Been an avid trout fisherman ever since.

Some years ago, I realized that trout fisheries are fragile. Switched to Catch & Release. Learned that the quicker a trout is landed, the more likely it is to survive after release. Now fish mostly Tenkara-style, mostly nymphs, with an extra long (11+ ft) fixed line. (No reel) This technique brings fish in much faster than with a reel.

Now live in NC and enjoy the mountains very much. Largest to date on Tenkara was a brownie about 22" that our guide (tutoring my daughter-in-law on the Watauga) was certain I couldn't land because he "knew" that Tenkara was only for small fish! From hookup to net was just over a minute!

Are you having difficulty with the mechanics of casting, or with presentation of a fly, or with getting hookups? Do you mostly fish with floating (dry) flies or wet (submerged) flies?
