Guys,

These things always evolve.

You can now buy (for the last fifteen years, at least) jig hooks with a 60 degree bend. They also have some at 22 degrees. Gamagatsu even makes some that aren't 90 degrees.

If you don't like mail order, the Sportsman's Warehouse near me has many of these hooks hanging on the rack. I'm sure other places (not fly shops) sell these hooks.

The beauty of using a jig hook for this style of fly is that it keeps the hook point riding upwards and the 'shoulder' of the bent shank helps the fly walk over obstructions better than a straight eye or TDE hook.

I've never had hooking issues with a 90 degree hook, and I use them for a variety of such ties, but I also have and use 60 and 22 degree jig hooks. I like how the 60 degree hooks slide over stuff, and the 22 degree hooks are nice if you work a fly horizontally through lots of cover (still needs a weed guard).

I typically eschew the cone head, and use dumbbell eyes, and find no loss in effectiveness (maybe the reverse) on these 'jig' type flies.

Good Luck!

Buddy
