+1 Hay's the man you want to be hooking up with for advice!
You have access to a large learner board so that is a bonus, I would be looking at a freeride/freestylewave board around 115 litres. I own a 116 fsw and its pretty stable and easily uphaulable in rough water for me (95kg)
Make sure the width is at least 64-66cm for stability. No need for anyhting flash either, jump on buy/sell and grab something for $200-300 as long as its a modern shape - 2005 or newer???
