here's a snapshot of a tiny part of my spreadsheet the measurements are all in cm and you can see all the lines shrank by about 10 to 20cm.
You can see the entire kite shrank by about 5% pretty uniformly over the kite with the A and B's having the least shrink. The a's shrank by 10cm, b's 14cm, and the c's by 18cm and the z's by 16cm. This is quite a lot but if you subtract everything by 11cm which is how much the A's shrank, because after all it's all relative not absolute that matters it's 0 shrink on the A's 4cm on the B's 8 cm on the C's and 6 cm on the Z's. This is well within the capabilities of the flysurfer adjusters to handle. My kite has a lot of hours and wear, broke both of the B bulley lines, broke the pulleys too replaced them all snapped several lines several canopy repairs. Not sure of the exact amount of hours but it's a lot. Now you might expect that the wingtip Z lines shrink the most of all the Z lines especially the Z lines near the middle of the canopy, but I saw the br1 and br2 lines shrank by 18 and 17cm while the br9 and br10 right at the tip shrank only 14 and 15cm, so that was the opposite of what I expected.
In anycase after fooling around with this kite for countless hours, making all kinds of mods, I eventually threw out all my pigtails and just kept shortening the B and C adjusters until it flew properly. The kite was so leaky that when I landed the kite it layed perfectly flat before I even rolled it up. I eventually coated everything, adjusted the B and C mixer and now it flies properly.
What's the moral of the story? I guess while they do these little 1 or 2cm pigtails for racing kites for normal kiters it's not worth changing it until it's 3 or 4 cm off spec. It's a hell of a long ass job to measure all these lines, took me 6 hours at least and after all that I eventually just used the stock mixer no mods and adjusted B and C until it flew right by feel, not by looking at the markings.
Pretty much every problem that an old kite can have, my kite had it. Still I suspect it's possible that downunder's problem might be different. This bridle is relatively new, his kite holds air, but it still has wingtip folds, so maybe something happened when he dragged it on shore with a half ton of water, so maybe his kite has some other problem. Lot of trial and error for me that they don't tell you about in any of those smartly filmed videos by flysurfer. Once your kite is far away enough from spec you can't line up those long and short mixer things you have to do it by feel, or you can do like I did and measure every darn line.
my 12 is all old and beat up and was a chore to get right. my 10m by contrast is brand new and an absolute delight to fly, no adjustments yet after flying it hard all year. New kites are great doesn't matter if it's a tube or a foil
