Too true HD - I almost lost a finger with my first Flexifoil which was supplied with Kevlar line which is now frowned upon I understand...not realising the line was wrapped around my finger I released the kite and the line ran and clean cut around two thirds of my finger right to the bone...
The irony being that when I went to hospital they said that the heat'friction of the Kevlar line had cauterised the cut and it was in fact sealed by fluorescent pink Kevlar...still have the scar today!
Have a buggy myself which is great for the beach...
