Just came back from Solvenia, had a head on crash on a mountain road in a car after just one day of paddling.
Found snowcard to be great - they got me back home early (on the basis that I couldn't paddle any more with a broken foot), rather than a medical need.
They have a great assistance team, who were really helpful when needed.
They may not be the cheapest, but if I go again at some time I will use them again. They are worth it...
