Stocked rainbow trout is what I tried them on and WOW did I hammer them . The folks watching were looking at me like I was nut for sure since I was using a crappie presentation technique that's never employed for the stocked trout down here .
I used a pinch on Comal float and a 1/32 minnow head number 6 and ran it about 3 foot under the float with a Patriot Go Go minnow on it .
I would long cast it and just creep it back to me at a speed I knew would flutter the tail and WOW did they hammer the fire out of it !
Started before the sun came up and was home in time for breakfast !
Managed to ketch and release a hundred pretty easily in about 2 and half hours and they hit EVERY cast . Of course absolutely no one uses a float for the trout here and several were asking what I was using and I told them ....
a crappie jig and Go Go minnow
