I always bought straight line products and had their launch pads until a friend got the fly highs. Wont ever deal with a launch pad again unless they change the way they are made. They have chambers in them and you cant get all the water out without moving them around. The fly highs i use are the side sacs. Some sites rate them higher than 440. Personally I wouldnt doubt if when they are full they are closer to 480. They fit perfect on both sides of the motor and dont really fill higher than the gunwales (spelling ?) That and you can walk all over them and not worry about em. The launch pads definately bulge when you step on em. I dont think you would be unhappy at all with the 440s. That pic was actually taken with just me in the boat. I didnt fill the drivers side sac but about 3/4 of the way full so I could have it balanced without an observer when I rode later that afternoon. I weight 210 pounds so if it was 3/4 of the way full that tells you right there that the other side was more than 440. Put 2 observers in the passenger seat up front and its even better. Since you liked the last pic here is a pic of the boat loaded down, as you can see it could handle more, but 2000 pounds is more than you will ever need once you ride it.
(and before anyone says anything, no I dont want to put a tower on it, I really like the old school look. The pole has its perks at parties lol!)
