Dave - a couple things...no chance the Polar was deeper than the Quasi. Just, literally no chance. And equally, there is no way your Quasi is "as flat as a Chocolate". PS boards are in no way, shape or form as flat as Crail boards. Not arguing with you, just telling you don't know what you're looking at.
usually i'd agree with you and i don't try to argue or e-beef(is that new?) but i had like 4 of the habitat "pack and go" series boards, all 8.125 wide- got them from my local shop, then i saw a couple other ones at another shop in town and ordered 2 of them because i liked the shape/concave sooooooo much on the boards before an they lasted. but when i got these 2 boards the shape was way more mellow/flat than the previous 4 i had.
you know about when the shapes/mellowness depends on where the boards are in the pressing process?
i don't know if i go way out on that, but bottomline of what i wanted to say is: i had rather steep and mellower habitat boards and i had some new alien workshop boards that all had way deeper concave- all PS produced!
