I think that is a good call. As a point of reference, targeting largemouth with a fixed line rod is out of my wheelhouse, but I have years of experience fishing for them with rod and reel.
There are aspects of swinging a tenkara rod that make the experience more enjoyable. In general casting experience is pretty high up the list for me and I tend to like rods in the mid twenty range and lower. The thing to note is that for trout, I cast a lot, so that priority may be different for you.
One thing about largemouth is that they dont tend to spook easily and are not lineshy so you can probably go with heavier lines amd heavier flies. Longer rods might be worth a look as i feel they are good for to absorbing short runs that bigger fish like to take. The reach of the rod and its length gives more resolution to throttle pressure on a fish. With a short rod you may need to move more with the fish and absorb surges with your body and position. When I say longer rods, I am speaking of rods in the 450-500 range.
I think the rod you picked will be really fun to take on bass…also if you get a big one a real challenge to land.
