Hi Guys,
Whoa, so much interest in Edges seemingly all of a sudden. I'll do my best to address all concerns.
Rebel's vs Edge's
The Rebel is a great (the best?) freeride kite and does everything really well. It will race well, goes upwind well, boosts huge, rides waves reasonably well and is easy enough for any level of rider to enjoy. Some schools even teach with Rebels. The reason why this kite is so easy for everyone, is the ability to let go of the bar and the kite will stop producing power, you will slow rapidly and drop into the water and be safe.
As stated in the previous post I made, the Edge is a true performance kite, a beautifully designed high performance wing << (word chosen deliberately). The Edge is designed to race and produce it's power very forward in the wind window to make edging raceboards upwind effortless. Gusts are instantly converted to acceleration, not downwind pull. This will push some peoples comfort zones due to the fact that if you are riding fast already, you will likely have plenty of edge in already, then instantly, you accelerate forwards, often dramatically increasing your speed. Sheeting out the bar will not throw away the power like the Rebel.
The Edge will continue pulling FORWARD quite hard. As mentioned earlier, you can release the bar to reduce power but to really get it under control you need to bury your edge and just force it back upwind. This can be a challenge when you are already riding at 25 knots board speed!

If you hold your edge, the kite will come back and you'll gain control, but it takes a little tenacity to stick with it when every cell in your body is sh1tting bricks and preparing for a high speed stack. To me this is part of the allure and challenge.
Like trying to get a wild horse under control.
Again, the kites are both great performance kites but the areas the Edge is designed to work will smoke all challengers; Lift, float, apparent power, smoothness and amazing upwind angles. The Rebel will give better turns, faster redirect, better surf handling and better on/off power by simply sheeting in. Rebel also boosts big and is a better allrounder.
They are two totally different kites but share many great attributes. The Power between Edge and Rebel is comparable but they produce power differently. Rebel has sheet in, instant power and the Edge has "wind it up" type power where you increase speed and sheet in as speed comes so does the power. This is whyRebel is better in surf and for general freeride, you can instantly turn power on and off like a tap and is fast to change direction.
You need to demo, because I could write thousands of words and in the end they are only words, whereas a few hours on an Edge and you'll get it in your bones!
