New tube

So last Wednesday we got the boys out to the boat club for the first time this year. Blew up the new tube and took it out for what was suppose to be a shake down run to see how the tube reacts. At first I took it nice and easy with the boys signaling to speed up. So after a few short rides with the boys switching places we got a lot more confident with the new tube and started going normal speed as we have in the past. But the new tube caught big air and launched all the boys off - they went flying. Shan had a small heart attack and I was in BIG trouble. We scooped the boys up with all of them laughing saying..Again Again! The new tube is a work in progress and the boys are up for dialing it in, but not sure Shan is?
