I finally had a chance to give my new sail a good work out today and I have to say I am impressed.
Bearing in mind I only have one other sail to compare this with, I am using it on a 155lt GO (a little big for real performance) and my technique is very average to say the least, here is my assesment of this sail.

1. Its a great looking sail.
2. Its very easy to rig and I dont have to bust a valve when downhauling.
3. It has good acceleration. It seems to take off quicker than my other sail (although they are 2 totally different designs)
4. Very forgiving in gusts. I dont feel like I want to catapult every time a big gust hits. The power seems to be lower and just shoots the board forward instead of trying to throw me over the front of the board.
5. Sails nice and close to the wind when tacking upwind.

I cant wait to use it on a smaller board... thats next on my wish list.
