Today i made the misake of using a cheap sale Bought and never used before, mk1 vx 5.5m. I did not have a same make mast so used a tushy 430 with 28cm of downhaul which turned out to sail like a door as no soft leach at all, and first board 63LT missle,24 drake fin, no comfort, no speed. Should have bit the bullet and got the speed 44 isonic out. I came in and changed to 44 speed and the wind came around to 315 degrees and a justa few runs as the chop was now to rought for comfort so came in again and changed to warp 80lt and same sail. Had my fastest runs on this and sail was much improved on the comfort. Amazing windy day with a few top speed sailers from abroad, vincent Valkenaers ect and other fast uk speed sailers, I missed out on getting in 40 knots as bad choice of equiment, always another day.
