I've been on BJs, longer and shorter, pretty much whole winter, except carves on my new Tinkler and Pogo, and letting all voluntarily folks ride them. For me and for my style they are amazing boards.
I would describe board as what you will get when you take best parts of two great Priors, 4wd and Metal WCR :D I've been riding them during season on every other surface except on real powder, that is due poor luck with snow, and found that board works like charm on hard surface which some folks call icy untill bumby softie spring flush, we had both on last week Ylläs CarvingCamp.
Boards can be ordered directly from Prior to avoid extra taxes and shiping costs. Drop me liner if more info required, i dont like spend bw here
