I had one & didnt like it at all. Very small wind range from not flying thru to overpowered - like about 4 knots. Leading edge is bloody massive...consequently they are a bugger to edge to the side of the wind window..mine also flew asymmetrically - so needed to have longer pigtails on one side of the kite to the other.

I now fly a high aspect 18m as my big kite & love it - huge wind range, especially with the 5th line, cane edge it to depower...
