I would like to add this as well. confidence in your lures and presentation is 98% of crappie fishing. Capps and Coleman use straight abardeen gold minner hooks and they have won the crappie masters 7 times so i would imagine they have a lot of confidence in there set up and im sure they have never used a gnat.
also I would like to add I googled the word gnat the day I tied the first one and a teaser,streamer,or tippet never popped up so I decided to call my little hand tied sickle hook a gnat ...thats it ..big woop
