For what it's worth I swear by my Sailworks Retro's and Revo's (revolution). The Retro's are camless freeride, I use a 5.5 and a 6.5, the Revo's are more blasting and B & J. I use a 5.2 and a 4.6. Great wind ranges, super easy to rig and get along with.
Great sails, well made and they last.........Best sails I've ever had.
The Australian dealer is in Victoria, Windsurf Systems.
think you will find there are a lot of fans of the Ezzy Cheetah, for Value, Availability, Range, Durability, Looks and easiness to rig and sail, and they are quite fast.
Severne NCX seems to be a big favourite also, I have recently acquired one, from all reports it's supposed to be a 40knt potential sail.
Looking forward to some wind coming up soon, so I will be able to compare between the two....one day when it gets windy!
There are quite a few reviews on both sails in some older threads on here.
