Odd Numbered Hooks

[Byron haugh]

I often wish the hook I am using was a bit smaller or a bit larger, but not a full size different.
While in Blue Ribbon Flies, I bought some size 15 (as I recall) hooks and really liked them.
I find that the size 16 hooks are a bit too large and 18's are a bit too small for the patterns I tie for PMD's and BWO's.
I just found that Bob Marriott's (spelling?) site carries size 17 dry fly hooks. I ordered some. I think he carries them in odd sizes from 11 to 21?

anyone else yearn for the odd sized hooks?
