I'd say ride some crappy boards so that you will appreciate the awesomeness that is the Evo (funnest board Ive ridden) but really you might as well just get one. There's no way on God's green earth you'll be disappointed. It won't be a board for hard carving or bombing (it will cope but not excel) but for all round freestyle it will help you improve loads and you will have so much fun riding it.
Probably buying a Westmark in the next few days. I'd probably recommend this more as a first board as it is a bit stiffer and will be better all mountain but if park is your preference anyway you would love the Evo.
I bet the blacklist would be fun too mind!!
If it's a real goose, is it propaganda?
