Take a look at the Lightwave WING. EXtreme upwind performance, handles chop real well, and can even ride toeside. The new graphics are a must see. Can be seen on the www.Globespirit.com
website, or just google it. I have had the Spleene Door, Jimmy Lewis Flightdeck and Slingshot Glide, the WING outperforms all. The new model has some good flex, flat in the middle and slight concave on each end, and very lightweight.
