should i buy the dna or the bio and which board the 3ds, premier, murray. etc. has to be hyperlite im getting an awsome deal. and what size i way between 175 to 180. thanks.

Man that is a tough one without more info about your ability, skill and style of riding. Any chance you can demo these boards? Demo is the best way to decide. For size, I'd say 140ish.

If your hitting sliders I would go with the Bio.
