Long rods, thin tippets, small flies - it doesn't get any better.
I have been asked repeatedly for size 28 and 30 hooks. The size 30 Varivas 2300 Ultra Midge hooks are very nearly as small as the Tiemco 518 #32. They seem to be a bit finer wire and perhaps a bit more brittle.
I have not been able to get the Tiemco 518 #32 for a couple years now.
Box of 30 hooks
The Daiichi 1110 hooks in sizes 26 for the smallest fish, and size 20 for larger micros, small sunfish and small trout are very well suited to tying black or white Killer Buggers. The black is closer to what the fish actually eat, but the white is easier to see when sight fishing. I have fished them with and without bead heads, but I generally use bead heads to make sure the fly penetrates the surface tension.
I have also had luck with Stewart Black Spiders tied on the Daiichi 1110 hooks.
The only time I have found micros to be selective regarding flies is with the Killer Buggers. The fly has to have a tail! When fishing with a Killer Bug (no tail) instead of Killer Bugger (with tail) my catch rate went way down. The tail does not have to be more than 2 or 3 or 4 marabou feather barbs, but it has to be there (at least in my experience).
