Rick, that's awesome that the LMB have started hitting the feed. I can see some cruising below my BG while they eat, but have yet to see a LMB take any of the pellets.
I suspect most of the forage fish are going to get eaten, and I certainly wouldn't think you'd want to be completely rid of them, so just keep an eye on things. One thing I've picked up here is that more often than not, it's a better practice to take little steps, then sit back and observe before you do anything else. The changes can sometimes take a little while. So I guess my point is that you have a pretty good mix of forage and feed, but it also sounds like you have a pretty good concept going right now with using the smaller fish you're pulling out as bait. Give that approach some time and see what it does - besides, that sounds like a great way to spend time with the grandbabies!
