This is not exactly what you guys are talking about, but here goes... I fish for hybrid striped bass here in central MS in a tail race. We must make very long cast... Sometimes in excess of 100 yrds. (And yes, I have been to a football field to check the distances.) We use a float called a Launcher M3M. It is a 1 1/4 - 1 3/8 oz, can't remember exactly. We use long rods and braided line. They make several smaller versions that could be cast with a crappie rod or a stealhead rod. The launcher is made by the same people that make Flexcoat. It is the rod eye epoxy. Roger (flexcoat's owner) is very knowledgeable about long distance casting a cork. We throw the m3m with a leader and fly or small jig about 85 yrds. He has setups that cast much futher. Hope this helps.
