Size #2 & 3 work really well for me on crappies. My top 5 colors would have to be glow tiger, florescent orange, perch, chrome/blue, chrome/black. No need to tip them with bait. The LM bass seem to really like them too. #5 & 7's for walleyes. My top 5 colors for them would be glow tiger, chrome/blue, chrome/black, gold, and perch. Usually need to tip the treble hook with either a whole minnow or minnow head.
