i can tell you about 2012 cat if your interested. i have an 8m
Would love to know how they compare to the Rally - if you've had a chance. I flew an instinct light once & it was the worst kite I'd ever flown so I've been worried about this kite being too similar. Too soft on the wingtips & miserable for boosts. I've heard my assumptions were all wrong tho.
Based on the flyer above - maybe they've beefed up the leading edge due to issues with too much flutter when its loaded hard?
