That's quite a question! If I had to narrow it down to 1 bait, 1 mold, 1 color, for every type of fishing I do, that may be accepted by every species I pursue...hmmm...off the top of my head, in short order, with honesty and confidence that it would produce across the board...I'd have to say the Super Stinger in GO-Shiner, rigged Weedless/Weightless, shot in Soft.
Do You see what I see?...
