Lots of smallmouth in Roosevelt Lake and Apache Lake, both on the salt river upstream from Phoenix. First smallie I caught on this pattern was on Roosevelt.
I now spend all summer in Colorado, just outside of Durango, at Vallecito Lake. It has a solid population of smallmouth, as well as some world class pike. That's where I do most of my fishing now.
Jeff,
Mine float back just fine, but not with the quick bobbing action of a Rapala. If you want that kind of action, you want a fly like the other ones posted or something like the one I'm posting here. This one is done with Balsa, and works pretty much like a Rapala when you give it a good jerk or strip.
