What snowboard should I buy?

I’m finally (I think) I’m done growing, and I’m considering the snowboard I should buy now instead of the Craigslist cheap pre-owned boards. I don’t think I am living up to my potential on the board I have now. I am 16 years old and 5’10-6’0 ft tall. I am an intermediate snowboarder that has been snowboarding since 3rd grade. I love to bomb the mountain and especially love to pop off the side hits. I am not the most confident when it comes to big jumps and I’m beginning to get into rails. I’m looking for something I could bomb that mountain with good stability and preferably a camber profile. Could somebody help me out?
