I've been flying a bunch lately, mostly my "new" set of used Pros! But in my bag was this sleeve that hadn't been opened in quite a while!!
So one day when the winds were only so-so, I opened this sleeve and out came my old Rev 1! Now this kite came with a 4 wrap frame, 11" handles, and 150# lines! I used to fly it at festivals, but only if the winds were perfect for it! And this was many years ago!
Over the last few times out, I put the Rev 1 on my 90# lines with 13" handles and the only light wind concession, was that I had put a Race frame in it! I'm remembering how much fun that kite is!! Yeah, I know, it's not the latest, greatest, thing out there! My Pros are proof of that!! But it did kindle the fire that burns in me today!! Oh, and did I mention how much fun that thing is? Not a light, no pull feeling on the lines, but a solid tug, even in light wind! Now I know why this size platform was picked to be the basis of the Zen!! Big, solid, and still responsive to the touch!!
I have had an SUL for several years now and use it in really light winds! With its lighter LE pocket, 2 wrap frame, spectra bridle, it weighs about as little as you can get away with and still hold up to gusts at times! With skill, you can get this to fly in very low wind conditions, but it doesn't fly itself, you need to have some practice on light winds to enjoy!!
You can put a stronger frame in it, but you also risk stretching the sail out! (My experience!)
It did make an affordable option for light winds over a Zen, but I'm saving my pennies for that one next!!
Since you've already seen you need longer top leaders, remember the link to see what you're looking for! As Bob said, you're looking to make the kite neutral, drive wise! Might be more difficult to launch, but much easier to control flying!
As Bob has said, the "push/pull" of dualies is not needed right now! You will use it later, but to a much subtler amount! We used to joke about giving noobs a pair of handcuffs to wear, as they learn to fly! Impossible to use that "push/pull" style!
Simple beginning exercises - take off 5' high, hover, land on both tips. Multiple times in a row! Got it? Go higher and do the same hover and landing routine. Practice til you can launch to the top of the window and back it down under control, landing on both tips, almost everytime! You start to feel the kite telling you what it needs to straighten out!!
The SLE tubes are stiff, so stiff that they hardly flex and that's the problem! The sail is cut to allow for some flex and create that "ball" of power in the center! Much less control results!! The UL (3 wrap) spars you have, are plenty strong to learn on!! Just remember to Give to the kite if you're about to crash, don't pull!!
Sorry to have caused such a mess in here!!! I was only hoping to get some simple comparisons of the 3 meshes, to show the differences between %s!! No tech info, no exact measurements, just simple pix representing the kites, so we could see the differences first hand, in one place, that's all!
