It may just some kind of reverse circle spey or something, but I can’t find any video of it.
My casting arsenal is fairly limited. Last week I was fishing river right with a pretty nasty downstream wind. That means double spey, a cast I have never really loved because it seems to lose a lot of energy on me. I throw out a particularly bad DS (i.e., not worth fishing out and that is coming from someone who fishes out nearly all of his bad casts). It was not my first cast like that either. Purely out of frustration and without really thinking about it I threw the line in a circle toward the opposite bank, landing my anchor downstream (and thus not hooking myself) and then automatically loaded a D loop that was far superior to what I usually get on a double spey with the resulting shot across the river that went ca-chunk when there was a lot of power still going out when I reached the end of the line I couldn’t get out with my DS.
I started playing with it and as the river level was pushing me closer in toward shore I had to bring the loop around and in front of me to keep my line off the rocks. But I’m using a pretty aggressive shooting head, so it was loading the rod even better (similar to a Skagit cast).
Anyway, as embarrassing as it is to admit, I simply don’t know what the name of my new go-to downstream wind cast is. Here is a professionally rendered diagram I commissioned.
1) RR, downstream wind line out casting right hand up
2) start rod with tip near water toward opposite bank excellerating as you come over the top
3) continue to move the rod tip to parallell with just upstream from your body
4) Then bring back to D loop just like a double spey (that doesn't suck)
5) Standard forward cast.
