Hi Magnus, we did a 5 day trip on Lainio Älven with a half hour helicopter ride into the head waters last may, fully packed and a mixture of white water and flat water, they worked great, you´ll be able to read about in the new magalogue from Kajaktiv next week. They are no rocket ship but they are super stable and can take a beating in the rapids. The cockpit is large so you can fish from it with gear between your legs. We even slipped the rods down beside us betwen the seat and hull on the sides.
A Finnish paddler used a basic version for record time along the norwegian coast, but again its not going to go fast but you can paddle more difficult conditions with the exception into the wind.
Anyone keen on paddling Lainio from the head waters contact Toni Franz in Kiruna, it was an excellent trip and you need only class 2 white water skills in higher flows using a yukon.
Best is go and test one, or rent one for a weekend.
Cheers
James
