forgive my ignorance, but what are the advantages of the different shapes?
is there a specific style of skating each shape is made for, or does it all come down to wheelbase and nose/tail preferences?
I know the narrow tapering tail was preferred for things like 360 flips (tre flips) and others have said they like a wider upper body / front of the board to have their front foot on, but a more narrow or tapering lower body to cut down on weight and reduce the heft of the board.
For some bigger wider or square shapes, there is a lot more room to put your foot without it slipping off the board, as well as more room to land on, as some people say too.
There is also significant differences between lengths and wheelbases too, which is good for those who want something a little more specific, eg I prefer 14.5 wb over 14 for a normal board, but others would be all about the 14" or just over, as I did with riding 14.25 wb boards back when I was more keen on tech tricks.
Given skateboarding is such a unique and individual thing, as much as there are the same tricks everyone does and some people can do those tricks on anything, from a 7.5 popsicle to a 9+ square or shaped board, the personal preference really comes into it a whole lot more.
This really shows in the Polar team too, with many people interested in how certain guys skate, what they prefer and how different their setups are compared to the same standard size, shape, mold of a skateboarder that mainstream media would portray, or that you would find in a mall store of generic brands, graphics and themes.
