You can't really generalize about deluxe shapes, depends on the batch of decks.
I've ordered 5 of the same graphic and the concave/kick ranged from mild to very steep.
Truth, but this is true of
any board mfg. I ride the AH 8.25 "larger" eagle when ever I can get my hands on it (which is 90% of the time), or what ever other graphic they are putting out on that shape (e.g. current Hewitt grape dope graphic). I couldn't even begin to count how many of the "exact same" decks I've had, but they are all
totally different from one another in subtle ways.
