I have one in my basment. I use to ride back in early 00's but overall it was kind of wrong evolution path. I moved to much wider boards (like swoard), and it is much better. I dont think i will go under 19 cm waist ever again.
Anoing thing is that skwals bindings does not work for angles i use now ( i think i will have to modify them in the workshop)
There is a list of reson why wider board is better but the most imortant is that nobody ask if this is a monoski.
