Although I tend to shy away from "still" waters ( if the waters don't move, I DO) , I , when despite my preferences, find myself in such waters, I have never had to lose sleep over bait specificity. I may not have filled my creel but i've never been skunked. The number of posts above and the variety of baits suggested are evidence upon which I rest my case.
On the other hand, if this was a tournament (YUUUKKKK), I may be a bit more choosey and do some serious investigation.
