The Surfari is a great board, I've ridden it in a range of conditions and it does most things very well but I must admit I did love it as a freeride powder board. It loved deep powder lines backfoot surfing off piste. I found it a little stiff though in tight trees, this bruise on my ass from 2 weeks ago is still angry and constantly reminds me of this. I also found it a bit much on hard packed groomers in NZ/Aus, more so when the resorts are busy. Don't get me wrong it can handle the conditions well but for me it needed speed and open faces and got a bit tricky dodging crowds.
I'm interested in the SG to see if it's a bit less stiff and more manageable whilst still maintaining the powder qualities of the Surfari, could be my deck board. Excavator is another I'm thinking about.
The Supermatics are great also, I would've been screwed last week with traditional bindings needing to sit everytime to strap in, I'm still struggling to sit properly now and in pain, obviously not what they were designed specifically for but it saved my ass literally.
