Well...
She has almost no snowboarding experience... nothing on a carver. l have personally been down the road of having a few different boards for different conditions but always ended up back on my 21cm waist free-carver(Sims CON 166) regardless of resort, terrain or conditions.
With that in mind probably one board only to start with... and it needs to do everything. The conditions at our local resort are mostly soft snow as in bottomless powder, machine groomed and then the odd hard packed day. Not really ideal for a carving board, l know, but l have been riding hard boots exclusively since 1988 and have no plans to switch. l had to ride softies for my CASI l & ll.... what a nightmare! No idea how l passed.... my evaluator must have been in a very good mood.
So yeah... a carving board that isn't a total pig in the powder would be cool. Any suggestions on length for her size?
