I never really keep track of these things (if I did, I think I would be depressed)...except for several weekends ago while I was fishing the Metolius River in Central Oregon, I ran into a great BWO hatch and even had the fly dialed in pretty good...I couldn't even hook a fish (I was something like 0 for 15 or so). at first, I thought I was short-setting them, but I brought in my little emerger (tied on a scud hook) and bent the hook out just a little ways and that made all of the difference. I immediately hooked and landed several fish before the hatch finally ended. Turned out to be a great day fishing dries in the snow...all it took was a slight modification of the hook. For the same reason, I like using hooks with a straight eye on most of my dries and some emergers...it seems as though my hook-ups increase with that.
oh, and yes, it seems as though the smaller fish do thrash about a bit more frantically than larger fish....
there's my 2 cents,
Randy
