I'm thinking about trying a used one one 2012 just to give it a go. Haven't used a gaastra sail for about 15 years.

Anyone had withe the recent models around 7m. Do they rotate well, good range? , is it a high tension sail? Does it need massive DH. Any known issues.

I have the 2012 vapors , 8.6 downwards.
They have a really nice balanced feel with a super high wind range . Rotation i have never had an issue with those that have tried mine have never complained or not liked it.
I have had my best results on my 7.9 with 98ltr manta , started carrying it out to 20+knts towards the end of last year(98kg driver on swan river), Ive become super comfortable on it .
If you follow the online rigging guide/video they are super easy to rig.

Good cheap sail, the owner only used it for half a season before he started a family,
