Chironimids are probably the only patterns that will produce all year long, but fishing them is SLLLOOOWWW, so I avoid it whenever possible. I should try the Stonefish method of full-sink line - I have heard that can produce much more aggressive takes. Now that it's springtime, I'm tying up a bunch of #6 conehead buggers, #12-14 hare's ears, and smallish muddlers. I fish small dries too, but I buy those, since I can't stand tying that small stuff. Also, never be without a few terrestrials (ants, beetles, etc.).

Around opening day on the planter lakes, don't be afraid to try a #12-14 elk hair caddis or stimulator, even if there aren't any caddis hatching.
