B16 is my favorite shape of all time and the shape I've skated the most of back to back; I think all last year all I skated were B16s actually. Every now and then I'll get a dud but for the most part they're amazing. I prefer the medium to flat ones though, flip tricks work better for me on them, the steeper ones don't feel as good; so when I'm buying one at the shop I always gotta stand on it to make sure its flat enough, and when I'm ordering a B16 online I just have to hope that it's not a steeper one.
@poor alice Powell's 8.5 × 32 shape is pretty similar actually.
