Although the parks is a 3-stage I would still recommend checking out the Hyperlite Marek.
even though its a continuous rocker, dont be fooled into thinking it wont have any upward snap that you loved so much about the parks. the Marek is an abrupt continuous meaning it has a smooth curve between your feet but a noticeable kink at the tip and tail for added vertical snap off the wake.
It also glides super fast and rolls onto edge as quickly as you can turn it. One of my favorite things about it is that it can generate tons of speed in a very short distance, which can translate into huge vertical pop. But it does so with a predictable boot and maintaining control. I have been having more fun out on the water than ever before and wouldn't trade it for any other board.
Hope this helps, good luck in your search.
