Love the madtoms, never heard of that pattern. I think there are still some smallmouth in Texas. Lake Texoma comes to mind, but there are other places.
Sparkling, blingy flies seem to be just the thing at times. One trip, my buddy was killing it on a silver spoon, but the borski slider was getting very little love. I put on one of the silver eyelash yarn redfish cracks and that help me bridge the gap and get some eats.
Other times, flashy stuff seems to have the reverse effect. I put in flash in most patterns, then tear it out if I think it’s messing up the eat. Tearing out the flash works enough of the time for me to believe too much flash can cause problems. That shrimp pattern I do is an example. Too much flash in it really dials down the amount of eats it gets. It never seems to work with a lot of flash, but a bright and shiny eyelash yarn crack will.
