new board - beginner

hey guys ive been researching for a few days on what kind of board set up to get and its getting me no where so thanks in advance for any info.

pretty much starting from scratch, im around 6 foot tall, weighing in at around 80-85kg
im a very quick learner with this kinda stuff so id prefer not to purchase a beginner only board.
i did the find a board thing on this site and its come up with the rio sports S... i just took a punt at how much volume i need, i really have no idea.

thanks again, adam
