The Mountain Shop here in Portland carries K2 as their splitboard rental fleet. I have used their gear for clients without their own splits and they seem solid...
You're talking about the K2 Panoramic right? I came really close to pulling the trigger on their full split kit during Evo's end of season sale last yr. Luckily for my wallet it sold out while I was deliberating.
