Hadders i am not surprised you get a Floating for ever landing when your on a 24 Solo, as it has a standard 130 and experiened 160kg max and you at 10 stone including gear allowance you would possibly only just be top end on a 21mtr, Dudek wings tend to fly better when to the upper weight end proven by my instructor numerous times, just my input and thoughts but good to hear others reviews of it.
