Looks like it could be a good jig trailer color to me. Nice looking baits.
Growing up in south Louisiana I am somewhat of a crawfish expert or at lest I've eat`n enough of em to be in the winter/ spring river crawfish's claw tips turn blue and their bodies are tan to almost white. In the sumer the hotter it gets'the red'r they get. Those look like an awesome winter craw match to me!!!
I like it - I really like that blue as well - care to share the recipes?
