Starting at the top of the line is the Forza 70 Master: This is the outlier of the group from a construction and concept perspective.
It shares the same footprint with the 70, but uses an Ash wood core to give it more power and strength.
Additionally, it comes flat with the intention of putting an R22 race plate and some version of a Rocker Race binding on it, giving it more of a race-like feel than the other models.
