Yes, I flounder fish a lot, use everything from 1/16 to 3/8 depending on current, wind and length of cast needed. Having said that, if I am trout fishing, I try to go as light as I can throw, without a doubt I catch more fish like that, have proven it over and over. Only exception I recall, is when fish are holding deep over reefs in open bay, with fresh water on top. Have to get heavy to get deep. I have Carolina rigged a jig in those conditions before, or fished a light jig under a cork ( as much as 6-7' ) in order to get the better action with a light jig, but have ability to cast and get deep.
