It's funny seeing companies going back to this idea. Perfectly symmetirical boards were an improvement in the times of the "Double Vision" model and the Hensley twin-kick, but back then the standard board had a tail that was bigger than the nose so those models were ahead of their time.
I haven't seen any of the Creature ones but I didn't like the look of the Mystery symmetry decks that were out a while back. I like a big friggin' tail, but slightly smaller than my nose (6.75"T and 7"N is perfect) but just as important as the size of the nose/tail is that they're shaped differently. I look for a nose that's a little more broad and tail that's slightly pointier than the nose. Again though, similar with subtle size/shape differences but differences nonetheless.
