I once caught a 6.5 lb bass on an inch of nightcrawler while pan fishing here in Indiana. That equates to atleast a 9lber in Florida. Does that make it a good bass bait? Not to start an argument but what data? For the most part big baits catch big bass. It is the simple fact that larger bass don't waste as much energy chasing their food as their smaller counterparts. If you were a big fat 10lber would you eat a small inline spinner or would you go for the large crankbait/jig/spinner bait/etc... going past? All I'm saying is that if it was such a great bait it would be used more often. I'm also not a fan of the small treble hook they put on rooster tails. Easy to throw. This all being said if you want to give them a try they will probably catch a lot of smaller bass and the occasional larger bass but if you want to catch the big ones you might want to upgrade to bigger baits.
