I'm looking into getting a second snowboard. I want one that is more of an all mountain that is longer than what i have to give me another option other than my freestyle specific board. I have a burton blender 145, but actually learned on a rental that was a 149. I'm a decent rider and i want to take a step up. I hear a lot of good things about the custom flying v. I'm looking at either the 148 or 151. i'm a female 5'4" 145lbs. Is this a terrible idea or not so much?
