Review on OBrien Super Screamer Person Towable by Angel Scully

This tube is a good size for two people and is easier to use than the three person tube we had before but there are two problems. First, we offset the inner shell and outer shell from each other so that the inflation valve is almost unreachable from the Velcro cover on the outer shell (see fix). The second problem is that it just doesn't hold air well. After an hour of tubing, he becomes noticeably lethargic. I doubt that in two hours it will be possible to drive it. Correction: Added star. is a zipper that allowed enough access to slide the inner shell and outer skin to align the fill cover with the Velcro access hole. However, it doesn't stay firm for more than an hour or so.
