It may not be obvious, but there is an advantage to being able to pole your solo at least in the shallow riffles, if not upstream in rapids.
That's basically where i am at. In my neck of the woods there a quite a few streams and small rivers, and even sections of larger rivers that are just too shallow to paddle in sections, but really just riffles and not really rapids.
About snubbing. All of the polers I know spend considerable time snubbing downstream.
Sometimes on a no shuttle, up and back outings, solo or with other polers. That no shuttle up and back style opens a lot of spur of the moment day trip opportunities for them, especially going out for an afternoon solo when the day turns nice and time opens up.
Sometimes poling downstream, shuttle vehicles set while accompanying seated paddlers. I admire their standing tall view ahead, their upstream work and play, and their occasional antics. But I lack both the necessary sense of balance, and the willingness to fall, into or out of the canoe, and never a poler will be.
I am envious at times, especially in downstream riffles and shallows where I can only get 3 inches of ineffective paddle blade in the water. They can push and glide and hull trim walk around, with a better view of the glorious 4 inch deep channel that lies ahead on river right.
I am likewise envious of folks who can side sleep comfortably in a hammock. Would that twere me.
