How heavy did your float bags come out? I've made bags of clear vinyl ala Yost and they came out ridiculously heavy. They didn't fit well either ... the stiffness of the seams caused the end seams of the bag to deform and crinkle inward several inches when inflated. I also used electrical fittings, vinyl reinforcements and tight fitting holes ... and the HH66 cement caused the vinyl to shrink outward and enlarge the hole ... and caused the vinyl to twist around the fitting when it was tightened. But ... they held air just fine ... they were just way too heavy and the fit coulda been a lot better.
