I've noticed on the last 4-5 AH's I've had from 2015-2016 have all been nearly completely flat boards. I brought one back into the shop I remember because I thought maybe I got a bad one but they were all like that. Seems like DLX has some extremely mellow concaves on Krooked and Anti Hero's and gets into steeper concaves for the Real boards.
I rode a shop deck that went through some wood source in Cali and the boards had a super deep concave. It took me awhile to get used to and then I liked it a lot. I felt I could lock onto my board better, but going back to the mellower DLX boards didn't really make me feel I could pop any more or less, or whatever. I don't know...I suck anyways. I nerd out on trucks and wheels more than my boards.
