Yessiree!!!
My best day ever fishing a Hendrickson spinner fall happened when I utilized a technique I developed to imitate the ovipositing females.
First I created a "Skating Hendrickson" pattern which is a reddish brown or creamy reddish brown synthetic dubbed body with a wide splayed Microfibbet tail, a centrally positioned, not too tall upright dark grey poly wing and it is heavily hackled with dun hackle, palmer style like an EWC with the hackle no more than 1-1/4 the gape of the hook...
Sort of a palmer hackled thorax fly...
When I fish it, I position myself at the head of a long riffle in the middle of the stream (conveniently, where no other angler typically stations themselves) because I knew the females would be dropping down to lay their eggs, usually with tons of barely noticeable fish picking off the spinners.
I grease the end of my line and the leader all the way down to the fly, treat the fly with my floatant of choice, cast directly downstream and hold my rod up as high as I can to keep as much line & leader as possible off the water so the Skating Hendrickson just bounces on top of the broken water as I dance it forward and let it drift back.
Deadly...!!!
If you are really lucky, there will be a light breeze that allows you to just hold the rod tip high while the wind re-positions your fly.
The first time I broke out this technique on a Pocono stream I fished one day in April until after 8:30 pm because the action was so incredible, I didn't want to leave. I caught over 40 fish that evening...
My Skating Hendrickson and a another color combination I tie to imitate Early Black & Brown Stoneflies are a must in my early season Richardson tray.
