Grab a chair and your own spot in the canal. Plunk some roe or a bug.
I do fish a couple other systems this way a bit but love the flow and can’t stay away from it for too long, and I detest level winds so no lol.
Have you considered using your other arm to cast and drift? You'll probably get used to it surprisingly fast.
Or use your off-hand to support more of the rod weight during the drift?
I was wondering how long it would take to get used to it, I’m not sure it seems like it would be hard. And ya, I do use my off hand to support the drift, as well as dropping the rod all together like a spey swing, but the latter lends to a rather sloppy drift I find.
This brings me to add that I HAVE recently tried fishing my 8 wt (it usually sits aside mostly for steelhead season, but gets all my coho and pinks plus a lot of chums and springs too)
I’ve just never been able to catch a steel on the fly, so I use what works. But casting that with my sore shoulder is no problem, especially when I adopt a Spey style cast. Seems to be the whole swing of the c.p. cast that aggravates my rotator cuff.
Maybe I’ll just fly fish, sell my pin set up for a down payment on a Spey rod
