Welcome,
Your intro is just a bit confusing. Blades are made by Flexifoil. What other Flexifoil kites ( and sizes ) do you have?
What do you intend to do with this kite? 4m Blades are really more of a fast kite than a jumping kite. Too small to float once you are lifted.
Actually a dangerous kite to jump with. I personally would not use it for that and I like to jump.
How big are you? What is the wind speeds you are looking to use this kite in?
Probably the best time to ask questions about a specific kite is BEFORE you buy it.
