Except you are wrong. Maybe try this. Ride a 150 and a 160 of the same board and straigtline it. Which one do you think will be faster? Even the 160 without wax will likely be faster than the 150 with wax. The gains from waxing in most conditions are marginal.
As to which boards have the fastest bases? IME Bataleon TBT bases are the fastest. Not because of material but because of the camber+TBT. Almost no drag in the snow=straightline rocket.
^^ This, its simple common sense.
