There's a few tricks to getting more pop or more stability out of your board. But it basically boils down to your weight and the size of the board... Longer boards are going to have less pop but more stability; shorter boards are going to have more pop. But if you have good weight control you can put your weight into your carves and get more stability.
And of course, if you want to go faster, try to find a board with a sintered base. It will hold more wax and of course make you go faster.
Might want to look at this board, I know a few people on here recommend it, and its pretty much good at everything: Ladies Choice – GNU.com
