Never been a fan of squarish shapes, but as others in here have mentioned, wknd's are pretty damn square. Got a wknd koston 8.5 deck that I got as a gift last year that I was planning on skating but the shape is just too square for my liking so it has just been sitting under my bed this whole time; it would just bother me too much if I were to skate it, I'm too used to B-16 style boards with rounder/pointier noses. I might end up skating it one day if I'm ever in desperate need of a board and too low on funds to get another one or something, but for now it remains tucked away in waiting.
But yeah, wknd, FA and hockey boards, and a lot of the more recent toy machine boards are all pretty square looking to me. I think it's safe to say pretty much the majority of the stuff that comes out of PS stix.
