I use eyes....makes me "feel" better is my only data used which drives emotions!

in the clearer waters i hit at times i have no doubt it matters
but with most of the texas lakes it probably isn't needed
i can say there are times when an unpainted jighead isn't the ticket for sure though
and eyespots are on almost all the best baits out there
so why not is my thinking on it

I usually fish jigs with eyes, but I don't think it makes much difference, they are just prettier.
