Hi, I have a 17'x39' (4' to 9' deep) oval composite wall pool that I'm in the process of renovating. The pool is located in Suffolk County, NY. I'm trying to decide between the Turbo Twister slide or the Adrenaline slide as well as natural gas vs heat pump pool heater. I'm putting in a new 8' diving board as well as an auto pilot salt system and Mod filter. Any suggestions will be mush appreciated. Thank you.
