You need to buy a user friendly board at your stage, the Styrotech were famous for being full-on performance boards, unless of course this is a new freeride version?
You need something wide, short and modern, something like a Starboard Carve 131 (I personally think this one), or 161 (would be next best), but F2, JP, Bic Tecno 66 (Good board, and they have a larger version), Exocet, Mistral, Naish, Quattro, all have similar freeride boards that you would love!
Width somewhere between 65cm and 80cm, Litreage, bewteen 120 and 160, length, between 235 and 255? to give you some ideas?, measure the Styrotech, Also important Soft rails to the front foot straps, avoid hard edged boxy rails, vee in bottom, some rocker, not a dead flat board.
Full Carbon, means they have used Carbon Fibre as the sandwich material for the divinycel, Herex foam, which means it's expensive, and very stiff, one of the top construction methods.
Hope this helps
