Re: bead sizes
Why worry about it at all?
You'll NEVER find an accurate 'chart' as there are too many variables in both the hooks available AND the beads that are out there.
I know it goes against the whole 'there HAS to be a 'correct' bead for every hook' thinking, but I'd prefer to 'choose' which bead I put on a hook.
But why can't you just pick the bead size you WANT to use, then see if it fits your hook?
If not, then go to the next size and see if THAT one fits.
You only have to do this once for a particular hook. Then you'd 'know' and there would be no guesswork.
You might be surprised to see that several sizes/brands/materials/styles of bead will fit every hook size/style. Besides, you may be someone who prefers to mash down barbs, and THAT makes more beads 'fit' for you than those that don't. Also, some hooks 'flex' more readily, and that can make a bead go on where a 'stiffer' hook wire won't. I find that I can usually get most reasonable sized beads onto a hook as long as I'm willing to debarb and flex the bend a bit.
This just doesn't need to be that hard. It's just fly tying.
What if we thought which particular HOOK you used on a pattern actually mattered????
Good Luck!

It Just Doesn't Matter....
