So i ended up ordering the big buzz flexifoil for my first kite. I was concerned about the material of the lines (dyneema?), so I called flexifoil last week and spoke with someone who told me it was dyneema that has been pre-stretched. This surprised me as I have read a few people here on the forums who were unsure of its makeup. Anyone have any comments here?   Now im waiting on it to arrive. I'm hoping that in low wind times it will be flyable by my Son.
