To sum it up in some one liners:
Try more adjustments till you find what works best for you and your style.
Ok, that's really all you need is those two things. Everyone had a different flying style which means that there is NO one single setting that is the perfect setting for everyone. If there was, then there would be no need for any adjustments at all. Rev would just put the kites out with one setting and everyone would be a pro.
I may be mistaken here but I would bet that even the members of I-Quad will all have somewhat different settings on their handles. Everyone is different in the way they hold their handles therefore you just need to try different settings until you find one that works for you. It seems from your second post that you are getting closer to finding that perfect setting.
As your skills grow you will probably discover that the setting that you have now may not be the setting you will be using later. Also, as the wind changes from day to day (or hour to hour) you may find that your settings and preferences will change as well. Again, try different settings until you find what works best for you. The more you fly the more you will know what adjustments you will need to make - just through the way the kite feels in your hands and the way it is flying.
That being said. Nothing you do with your settings and/or adjustments will give you more skills as a pilot. You can only gain that through flying and practice. The settings will make it easier to perform some tricks or have a little better control, but you must first have the knowledge of how to control the kite. That only comes with practice. One of the biggest problems with both the Rev's and Dual's is that the new pilot assumes that if they stick a kite in a certain position, the kite will do a trick for them and all they have to do is stand there and watch. With the incredible amount of control the Revolutions provide, this problem is greatly exaggerated. When the kite is flying forward, it creates a vortex of wind that flows over the front and back of the sail and provides what is called "Apparent Wind" - or in other words, wind generated by the forward motion of the kite instead of being created naturally by nature. This apparent wind is added to the natural occurring wind and gives the kite improved lift and control while flying. That is why you can keep the Rev in the air all day long while it is flying back and forth but when you stop and hover, the kite loses some of its ability to stay airborne. In very strong winds then this is not a problem but in winds that will barely keep the kite in the air, flying is no problem at all but stalling / hovering will cause the kite to begin to fall out of the air. The point I am getting at with this very un-technical description is that if you are flying in lighter winds conditions your kite will either fall out of the air or you will have to "MOVE YOUR FEET" to make up for the lack of apparent wind while the kite is stalled.
The kite isn't going to do what you want it to all by itself, you have to make the kite do what you want it to. If you want to put the kite into a perfect stable hover in light winds, you will probably have to walk backwards enough to provide enough wind to get the kite to hold it's hover. If the winds are very strong, WALK FORWARD to take the wind out of the kite so your kite isn't so twitchy and uncontrollable. When you fly towards the edge of the window (where the wind is less) you need to walk backwards to make up for the loss of wind. As you fly towards the center of the window, walk forward to reduce the increased pressure. You can actually hold the kite in a perfect inverted hover and by walking backwards or forward, get the kite to rise or lower without having to make any adjustments to your hands/handles at all! That's the secret!!!!! Get the Rev in the perfect position and use body english to control the wind (not your hands). Try it and you will be amazed at just how easy it is to hold a perfect inverted hover. Also, make your body movements smooth and very fluid, not jerky.
This is a very good thing to incorporate in with your flying and learning but as I stated in the first part of this post, body movement is not going to replace air time and practice....but it will make learning a little bit easier and quicker.
Ok, enough with the secrets for now.
Hope that helps.
