I would suggest making sure you keep some up elevator and dont let it rock forward too far on your takeoff runs and stay one stp ahead of it on the rudder. It will try and water loop if you let it rock to far forward if you floats are even slightly out of alignment (I know this first hand, atleast with the KMP floats). You will also probably benifit from adding an additional venteral fin. It made a huge difference in mine.
