hey Mojo...you are right about the exploding bladders on some...I was fishing one night about 7yrs ago back in Alaska using my pontoon kickboat...all of a sudden BOOM!!!! I thought I had been shot because of the violent splash of water and how loud it was...before you could say "Jack Dempsy" I had barrel rolled in 100ft of water still strapped in...nice and cold water if I might say so...well, I am still here but thats because of my force fins...
