No, I had just gotten a new tube (Muddler by Trout Traps) last year that had one of those cheap, lightweight polyurethane bladders in it. Those things are dangerous! If you get a hole in one, they deflate immediately. Lucky I wasn't sittin' in the middle of the lake. I've since bought a truck tire innertube to stick inside instead. As far as the chronny hatch, never made it to the lake, so I'm not sure. This cold weather may have put 'em down again.
