My experience was exactly like yours. I'm glad you took our advice on the Heritage too, she's a beaut.
I am too. For what it's worth, my friend who is at about the same level of riding as I am just bought a Jones Mountain Twin (coming from some generic M3 board or something) and while he notices how much better his new board is I don't think the difference was as dramatic as what I experienced. And remember, I'm coming from a Burton (albeit a low end one).
