To compare the Stone Fly and Caddis Fly 360 rods, there isn't much more I can say than what I put in my review of the Caddis Fly rods http://www.tenkarabum.com/caddis-fly-rods.html. There is another company http://www.tenkara-fishing.com/rods.html that offers rods that are very similar to the Stone Fly series - although their 12 footer is a 7:3 rather than a 6:4 and their prices are a bit higher but still below the Tenkara USA level.

Whether to drop down to an 11' rod or move up to a 13' rod depends largely on where you will fish. I don't know the streams you have mentioned. If they are smaller brushy streams, the 11. If more wide open, the 13. I suspect John Scott could provide some guidance here, as I know he frequently fishes with a 13' rod and it seems like he knows the streams you have mentioned.

I do sell rods on my site, but what I sell is not what you are looking for. I carry high end tenkara rods that sell for $345-415, and a separate line of rods designed to make fishing for small fish fun. They are in your price range ($57-82) but they are short (6'6" to 10'2") and are intended for fish that are just about on an inch to foot scale with the rods. The shortest rod is good for fish to about 6" and the longest is good for fish to about 10".
