Q-ball, a Place Diverter will give you a nice tail along with the ability to adjust the rid angle of the boat. I have also just installed a Place Drop Snoot which lowers the angle of thrust and lifts the boat, it also increase my tail when the diverter is full up.
If your just looking to shoot a tail and have a split bowl Place also sell a Rooster Booster for that purpose.
