Enjoying the interesting concept of Mike Tinkler to change the rocker line by putting more pressure on the back of the board and by doing so to be able to both turn sharp while accelerating swiftly out of a turn with the flexible tail on the Mistral Challenge Flex. At the last turn the aggressive turn even caught me by surprise Jumping with this board was 30 years ago already out of the question in order not to destroy the tail and the springs in the mechanism. And with times the plastic components for adjusting and holding the springs only got more brittle and rare. https://youtu.be/ZoxuP6FtSqs at 6m00s into this video you will find an early version of the flex tail on the beach in 1985. The Neilpryde RAF Speed "Fred Haywood" 6.4m2 always delivers power while staying in control during wind gusts. Only doing a duck jibe with the fat bottom on this sails requires longer arms than mine (4m55) ;)
