Ok so I have floated a few times years ago in Idaho and now am moving to Montana and will be doing alot of fishing and camping. I have determined that a 14ft boat is what will be best for my plans. I have been reading ALOT for the past month about boats here on the buzz. I will not be rolling or folding up my boat for storage so thats not an issue. I think I have my choices down to AIRE,Maravia or Sotar. I hear the things about the AIRE's as to silt/sand in the bladders and zippers but I am wondering is that really an issue in MT where the water is "mostly" clean? And are the Maravia or Sotar warranties as good (no fault) as AIRE's? Also is it as easy as it looks on AIRE's website to clean and maintain them? Are either Sotar or Maravia even easier to maintain? Thanks in advance for your input. MTMonkey
