I've got a 7ft ulatra lite spinning rod with a real nice medium size spinning reel, it's my redneck flyfishing rod! I love to catch Bluegill with it.
Most everything I've read say's to not keep any Bluegill if raising big Bass is your goal, especially in the first few years of pond development. That's not an option for me, I'm excited to hear that your Bluegill are doing good with the Tilapia. Tilapia provide forage for the pond, maybe give the Bluegill a much needed break, and eat Algea.......doesn't get much better than that.
If wishes were horses, dreamers would ride.
I must admit that I am not a fan of the Catfish
