they are game changers in my book. I picked up a couple Aire Lynx II’s (one for me and one as a loaner) and they opened up a whole new range of rivers. Luxury backpack style and they’ll support you for a week plus, no problem. As long as you stay away from sluggish hyside Ik’s (previous owner,sold it for a Lynx) and look at tomcats or Lynx’s then they handle great under load. A friend has a tandem tomcat and it’s an amazing value for the $$, as well. Paddling his for 5 minutes switched me instantly from Hyside IK to getting the Lynx’s.Do you solo the tandem? Been thinking about picking one or two up to use and hold more gear, but been indecisive due to size and handling.
