Matt H here from Auswind-
If you are looking for grunt and durability i reccomend you check out the Severne Renegade (all x ply, can be rigged full with a really springy feel) - which is surprisingly light for such construction and can be tuned to deal with windy stuff too. There are some excellent runout deals available - check out
standuppaddlesports.com.au/ for more details and pricing
You can take a look at a video of the sail in action here :
gallery.star-board.com/share_gallery/windsurfing_video/07_starboard_promo/virtua_sailor.mov The Renegade becomes the Gator for 2008- in the wave sizes the functionality holds the same focus (tough, light, grunty)
As a heavier rider (87 kg) i personally like the drive and early planing this style delivers! And with this construction i dont find myself making trips to the sail repairer.superfreak boujmaa Guilloul uses these to unleash his chaos upon the waves.
Good luck with your purchase decision.
