I agree with Calbs re. the Mana 10', at your weight and with a mal riding background the transition should be seamless.
Most of the crew on the Mid are very friendly and there are a range of boards that most guys happily swap around.
Also agree with Jarryd about the demoing and second hand. Most surfers who takeup the sport get hooked and are looking for their next board within a short timeframe. Initially balance is the biggest issue, but once that's sorted you'll be looking for the next board. My wallet's on life support

Happy to help with demo's, have a few different boards, just PM for a hook-up at the mid. As it happens I ride a Wayne Dean mal also
