A few tips that may help.
1. I like oblong floats with pegs or spring clips that I can adjust the depth of lure(s)<br>
2. light jighead IMO between 1/32 - 1/16 oz get the lure down and allow nice action<br>
3. tail shape makes a difference when float fishing. Curl tails are the last shape I'd use wherea spike tails, Crappie Magnets, float & fly and straight thin tails do well.
4. a low wind (8 mph or less) with a bit of chop gives lures a bounce; I move the float 1' ever so often for a gliding action whether breezy or still
