I have Just purchased a 154 Lightwind and have to say I am overwhelmed at how good it performs. It handles like a slalom board but performs upwind and down wind like a formula board. You can jibe it and use it all day without getting foot cramps like a formula board. I was planning with a 7.8m in 9 knots and was still comfortable when my wind guage read 19 knots still with the 7.8m up. I give it a big recommendation to those who like to sail when the rest of the guys are sitting on the beach waiting for the wind to arrive. I plane before the kiters.
