Like ScottP, I like the Dai-Riki 125 for smaller flies. The 125 is a straight-eye 2X short hook so the shank lends itself to tying smaller flies with the advantage of a larger gape.
This little extended body BWO is tied on a size 18 125 ...

... but even with the extended body it is about the same size as a fly tied on a size 20 standard dry fly hook. Lots more hooking and holding power than a size 20 dry fly hook to my way of thinking.
For larger flies, it doesn't make as much difference to me, although another of my very productive flies this year, Duck's Green Drake, is also an extended body fly tied on a straight-eye hook.
