I would suggest the old style round tube. I had my 10 yr old granddaughter in a float tube with the v back. As we headed off the lake because of wind, she got hit with a micro burst that picked up the rear and flipped her upside down. She was stuck in that position because of the stripping apron. Fortunately her cousin was close by on a round tube to keep her head above water till I could pull her up on my pontoon boat. Lesson learned.
