I learned to fish multi-fly rigs when I was a kid.
How to tie the Dropper Loop
My grandfather would normally fish 3 winged wets and that's how I first learned to fly fish. It's a deadly but little used technique to this day.
While we used whippy wet fly action 9' cane rods back then, it's not at all difficult to cast a multi-fly rig.
You just need to forget everything that's been drilled into your head about tight loops and a fast line speed
