In response to B's question: "So now to my question... I think that I might really like the boat, but it seems a bit too low in volume. "
Here is my experience, but first, I usually weigh in at 240 - 250 dressed in gear. 6'3", size 12 feet, 33" inseam. I've been paddling a SuperFun for the last 2 years.
The "Classic" SuperFun is more playful than the SuperEz (and therefore I'd argue it's more playful than the EZG60) - but it's NOT as much of a playboat for me as was the WaveSport T4. For me (devoid of pure skill and finess) - the front of the SuperFun is hard to throw down - though not quite as hard as the SuperEz .
The SuperFun isn't as crisp feeling while surfing as was the T4 and SuperEz. However, the SuperFun is SUPER easy to stern squirt, or even just throw the stern down.
I took it down the Main Salmon in mid June this past summer at higher flows (20,000 cfs) - and it was great. I also took it down Westwater when it was running about 6,500 cfs and had no problem there.
I can also take it down a small class II river and have a blast, squirting and splating from rock to rock, eddy to eddy, and catching micro surfs inbetween.
The "classic" Superfun is not as overall playful as other boats out there - but for me it works well for the following three reasons listed in order of priority:
1. All day comfort - unbeatable (at my size there aren't a ton of boats I can fit in well and comfortably - without sacrificing #2 below)
2. River Running/Playboating - allows me to run rivers without sacrificing the playbility aspect. Really the best of both worlds - though not the ultimate of either, just the best combo out there.
3. Forgiveness - not really a priority per say, but a great aspect of the boat. However, i think the boat is less "crisp or responsive" due to it being super forgiving.
