I think youre on the right track. The type of frog doent matter so much as the size and color. I also use booyah pad crashers and the h20 tiny toads. The pad crashers are pretty big compared to the scum and h20 frogs. Right now, in my waters, smaller is key. As far as colors, light or dark bellies, thats all i care about. Use one or the other depending on the lighting conditions.
Im pretty sure bass dont see what brands of frogs we use. Where im throwing them i doubt they even see a frog, just something moving on the surface, an easy meal. Not saying there isnt a place for the other types and brands of frogs, i just like to keep it simple and not overthink it
