Hi there, sure it works with a 5.3, that's about the biggest sail you want to put onto it - you can also get a second set of tri fins for it, either MFC TF 18/12 or 18/11, other some K4´s or other US brands - for when the wind is very light. The Quad is actually faster in a straight line and rides flatter over the water, much like in surfing - actually better for flat water when reasonably powered up. In lighter winds, the Tri setup can feel more "loose", but it's mainly subjective and we've tested many times side by side, the Quad actually planes earlier, but feels more locked in - good for the Gorge for sure with the chop and nuclear winds. So go for the 82 and say hi to Eddy! yes, that's a good combo he has there, the Gorge has such a huge range of conditions!
