Rick I have noticed when gills or perch slow down , I switch from wax worms my primarily bait to the green colored crappie nibbles which usually catches several quick responses - the red nibbles don't seem work as well - have also been known to switch to a single piece of sweet corn - don't laugh it works - pieces of slightly under done chicken fat, cut into strips a 1/4 inch wide and an inch long - small pieces of trout worms from Walmart and the list goes on. Yesterday I was using the black fly jig with wax worms. Noticed the fluffy part of the fly fell apart after a dozen or so gills and under the fluff was a solid black body with two white spots - talk about something that drew attention - it worked super - limited out on gills for the third day in a row.
