Well we did a number of downwinders in exmouth, it excels for this. I get in trouble for saying this all the time but by Christ the rebel isn't a wave kite. Those who say it is great need to get their ass on a REO / Neo and see what a wave kite really is. And it seems the dice as well. Still reckon, the REO has it slightly pipped but the difference for a mere mortal like me is irrelevant. The 2014 may have increased that gap but we need a back to back with both from the same rider on the same day if one is keen.
Robert the rebel is a higher aspect kite, with more swept back wingtips it will hunt the edge of the window more than say the dice, REO, drifter, BWS pro, best Cabo, etc etc etc....it is more efficient. Longer and thinner is slices through the window to the edge more (this is all in relative terms). You will never get the same bottom end on the dice which is ultimately based on a C kite platform. And also this efficiency allows you to spill power by getting it closer to edge of the window so you won't match its top end either.
Take the edge for example. By bro and I have had say the 11m edge out in stupid winds on strapless SBs. Like 10/ 11 knots and holding ground...yet we had them out in 25 knots, scary as hell the power in your hands, but doable, the wing didn't falter or do stupid things.
The rebel is scaled down compared to the edge but the same aspect principle applies.
My suggestion is you need to prioritise what's important. If low end is the top of your scale then get a rebel. Great you then can do your downwinders in lighter winds and have a sht time at it on a kite that isn't that great for that sort of thing. Or how about this...go a size bigger.
My 10m edge is now an 11m dice, easy.
Oh I still miss my edge though....
