I've decided to step into the modern world and pick up a Quad on my next trip to Maui. I'm 72kgs and ride a 76 litre single and an 83 litre thruster mostly in powered up conditions. I've read a heap of reviews and am leaning towards a 78 litre Goya or 80 litre OES. The other boards I like are the 83 litre RRD or 85 litre Quatro LS but would they be too big as my smallest board? I've yet to ride a Quad but common opinion seems to be you can ride 5 litres bigger with no loss of high speed control - is this your experience? thanks Steve
