Joking? Not me! Take a 15-4 and cut an inch off each tip, and you get a 13-3 1/2 or so!! Awesome pulling power and instant spool- up, but you can't buy one off the shelf!
Actually, I WAS joking, but now it's starting to sound feasible. I figured Citabria was trying to start another thread like the "Hovering" thread, with all the wise-ass comebacks and stuff. If he was serious, I apologize. Just wonder why we haven't heard back from him?
