Im still new to my 2016 Puma FTD Hull, and I know exactly what youre talking about with biting. I think I unlocked this on Friday at Toho running in the high 70s. I know my boatreally likes to run flat, too much bow lift and she seems to chine walk a lot more. So when running straight I usually dont go much, if any, over half trim. Now when Im coming into a wake or a turn, I have found I need to trim up A LOT to get her sitting on the pad and slide around the turns, then I drop the nose to reaccelorate. Like I said, I as getting her to slide mid to high 70s and dropping to quickly accelerate back to over 80. Not an expert here, still need a lot of seat time with this hull to get her down pat, but those are my lessons learned so far.- Chaz
