YesWould a mini disc fit the binding pattern on an unw8?
I’ve ridden my Pentaqurk 158 2020 on 2 occasions already. It’s a bit softer torsionally than the UNW8. If you charge and carve hard it can be a daily driver. Not really an open groomer board only if you have some responsive bindings.
Since I’ve finally ridden all three centrifugals, I can say that Surfari -> Pentaquark -> Unw8 (from the least to the most aggressive one).
