Having used most of the hooks available (and quoted here) and fished with them by myself and with clients I think I have now formed a pretty good view of the sort of characteristics I look for in a hook.
The first thing is not to get a hook with too short a shank. Even the old masters advocated a standard length shank and they added that the body should be tied short. In others no further than between the bard and the point of the hook.
The next is to look for a hook that is made of fine wire. Again, if you are fortunate enough to see some of the old flies (and I have seen hundreds) you will be struck by the thinness of the wire. After all, the really early flies were on hooks made by needle manufacturers.
Lastly, it should have a straight eye. If you look at these schematics you will understand why I think a straight eye is better:
So for me, the hook that I find the better is the Kamasan B525 (or 410 if you buy it from a fly shop):
As for tying attributes, I have posted these before but here they are again:
Now for some interesting news,
Partridge will be releasing their new 'spider' hook at the BFFI this year and it will have a straight eye.
Hope this is informative for you.
