3 meters? Thats almost 10 feet - I don't think you will find much on the market that large and cetainly nothing that will trick well (just too much wing in my mind).

Yes, I always liked that series of videos. I have a couple of 10 foot wings, great fun to fly & plenty trickable. They do need plenty of slack and start to pull pretty hard when the wind gets up around 10mph. There was a Firestorm for sale in the swap a while ago for a good price.... did anyone pick that one up ?
