excellent advise given below,...
the best way to find your own "sweet spot" is experimenting, ideally with a partner only a single variable being compared at a time.
Three of us took on the spirit kite when it was first introduced, what could we change to lower the wind range and improve control? We met weekly for eight months. The first few changes were inches at a time, compare, discuss, meet again next week to try something else. Always direct comparisons, which one did you "like" more? Okay adopt that change and try something else. I flew that design (we called our version a Tirips, spirit spelled backwards) for 3 years totally dedicated to NOT using a Rev shape.
Eventually we had the thing flying in our local conditions as a stiffer and more adjustable structure and couldn't find anything else to improve upon.
Harold Ames & I did a cooperative project in 2000, our kites are pictured in my signature. They locked together in flight thru the use of rare earth magnets and also flew in no wind with the SLE leading edge tubes. (talk about throw and catch?, it was a javelin!)
Those are called "Ryv 1.6". Its got a deeper center vee, longer down spars and a no-sew bonded production technique, there's no leading edge mesh, and of course a more responsive bridle (the 1.6) It's built closer to the sail at the center point and the hinge that connects the two pieces together is also reduced in size. Most folks would think it's a stocker, but less wiggle at the center. When you replace the SLE tubes w/P-90's it can fly indoors. We made about half a dozen prototypes, Harold would build one and I'd test, then report back, some things I wanted were determined to be unreasonable, some were outright errors. For example the kites had no elastic, knots or washers, instead we used built-in "belt-loop" and an oh-ring attachment method to tension the sail. Great idea, NO KNOTS to catch on when flailing. Bad idea because they aren't durable long-term. Oh rings are designed for compression, not to be used like a rubber band!
Sorry, this forum reply has gotten too long, the point is to have a fun learning and experimenting. A partner makes it much easier to compare side-by-side. Watch out for engineer-type partner geeks, they tend to change five variables at once and then seek advise about a sudden oversteer problem. Scientific principles, one variable at a time.
Don't think, "FEEL" which way is superior when testing. Try it in different conditions too, don't make a ten minute decision. I spent 8 months deciding to use the French bridle on all of my Revs. I tried to make my own too, they took like 4 hours a piece. I gave the design parameters away and buy em pre-assembled now Wrote the directions and developed a way to ship the components as well as identifying all the end points so it could be installed by anyone. It's not better, just different. (some like a stick shift and a tight steering wheel, some like auto trans & a love-seat feel on the road, some build their own vehicle completely customized for one purpose only!) Your ride will be best as you prefer it,... how does it feel to others? Who cares!!!
I live outside of the nation's capitol, we have no-stinkin'-wind, indoor conditions at least 3 full months of every year (but with an unlimited ceiling!) Every modification I have ever untaken has been about improving performance in no-wind, difficult conditions. 22+ years worth of stealing every good idea or technique I could be exposed to at home or on the road. Our club has some nationally famous builders, so new ideas show up about every month, active vents, removable vent panel covers, whisker reinforcing, leach lines, different framing and venting positions,.. like Thomas Edison most don't result in the invention of the light bulb. Every once in awhile though someone hits a home run. Dave Ashworth is the most talented indoor kite builder I have ever been exposed to, single or quad. He's never copied a design size outright, nor bought a kite commercially. He built his own handles too, but first made the router bit and feld a suitable tree!
