OK..
Horny Toads in my area are probably better than live shiners..
WHy??Because it's hot..you can cover alot of good cover quicker in these hot summer days..
I use a #4/0 Gatzukami worm hook..no weight at all.
Cast long and treat the frog as you would a rubber worm..the fish will boil...and then run ..when line is straight..set the hook..The frog will sink so fish it like
squish squish squish pause....squish squish squish pause..fish it in thick cover because it's 100% weedless...Big fish love this bait for some reason..

Color..I've only caught them on bullfrog..I have tried watermelon, pearl and a couple of other colors..to no advail.
My son Matt caught a 5 pounder on watermelon.
