Anhedral stabs give the same effect as a lower stab on the fuse. Thus helping roll coupling while keeping the stab from being blanketed by the wing. Canalyzers are not nonsense and they do help. They increase rudder performance and yaw stability. They do not necessarily improve every design, but they can help with certain designs. You can run less wing area near the tip, increasing snap performance and the canalyzer compensates for this as well. I personally am not a fan of them, but I am anxious to try the new BJ Craft episode. They obviously work as many designers, such as CPLR use them very effectively.
