all depends what you want from your kite and your style of riding, ive had some long sessions on the rebels to see what all the hype is about and although its a nice kite but it feels unrefined compared to the edges and had the same response from the rebels owner whos remarked how smooth and solid it felt in comparison, the last session we swapped was at the upper limits of the kites high 20s to low 30s 8mtr rebel 9mtr edge 2012s, not only flying but observing from the beach the edge looked a lot more stable in flight no surging at all and this relates back to you when riding, the boost on the rebel is more gut wrenching and requires a bit more movement of the kite the edge is a much more gradual climb and grunty boost and the hangtime lasts a lot longer due to its shape of wind , in the turns the rebel is faster for sure but had this bit of lag especially during fast carves and big jumping transitions, on the water speed the edge has it, as depower goes the rebel is better and this will relate to wave riding, the edge never really depowers fully and to ride on the waves needs a lot more board control ie edging or step down a size,at the bar the feel of the edges are a more connected feel which some people love or hate the rebel required a lot more bar control when flying your kite, the edge looks and are superbly made but the rebel has a lot more reinforcements especially in high wear areas this would be important if you self launch your kite a lot , the inflate deflate valve on the edges are imo much better giving you a much quicker inflate might not sound a big deal but i wouldnt go back to the smaller valves , bar and lines both very nice bits of kit i prefer the feel of the slightly thicker ozone bar with the finger moulds compared to the north bar, remember the ozone safety is a pull not push system which is more widely used,line quality not sure on the norths but ozone use the same zero stretch dyneema as on their paraglyders, rebels are on 5 lines compared to 4 which imo is a better safety system, but have heard of the 5th getting bar wrapped, hope ive covered a few things here to help , id also say your body weight comes into it for riding the edges and a good edging board will only make it more enjoyable, ivve had a couple of hours on the new rebel but prefered the latter model, i gave a good few kites a solid run last year but if all the kites were set up on the beach itd be the edge that id hook on to ,get a demo and spend a good few hours on each in the same conditions its the only way to truly make your mind up
