Eastland,
I'm not Bob but I did stay at a Holiday Inn Express last night.
I think Bob will tell you a 21 inch bass is not as good a predator as somewhat smaller bass. A 21 inch bass wants larger food and not as often as a smaller bass. From the literature I have read and from my observations 14 to 18 inch bass are the eating machines that crop down forage. You want the 14 to 18 inch bass to be able to crop the crappies down (no pun intended) before they get out of hand.
The only way I would feel safe having crappies is to have a bass heavy pond. That is what I have but I feed and sell my bass when they are 2 lbs. plus and add many each year. I don't depend on reproduction and would prefer my young of year bass get eaten anyway as they are not pellet trained and will not grow as fast as my pellet fed bass. So no worries about the crappies eating my small bass.
