Which float tubes allow you to easily deflate and Mouth inflate while sitting in them? I posted a similar post a while back, but let me narrow down my qwest. I'm looking to do fish some hike/mtb in lakes this spring. The caddis navigator IV looked decent, light and has a mouth tube. What else do you guys use? Weight is not the primary concern. My fishcat4 is a bit heavy and i don't trust the boston valves for deflation while fishing....a half turn too much and you would be sinking fast!!
