No clue. However I bought one of their brand new boards last month and I can give a bit of feedback (I’m no expert and the info I provide are based on my one month experience)
I bought Josef’s board in 8,5. It took me 3 sessions to get used to, but overall I dig it and as a first time sour customer I have to say I’m pleased with their product. The shape and concave are somewhat mild and the nose/tail difference isn’t too apparent, big change from what I was riding previously.
I usually ride street and I do plenty of gaps, stairs etc. Also ride miniramps from time to time and the board holds up really well. I have a dent on the nose after repeatedly zipping out and smashing it in a stone wall but overall solid wood. Their graphics are also sick
