Windsurf UK has heaps of reviews on FSW boards for the last 5 years
www.windsurf.co.uk/Don't discount older boards, for my weight of 70 - 75 kg I have 2008 JP FSW 101 and FSW 84 and they are both sweet in rough conditions and pretty quick.
Maybe for you keep your 96 and get a 70 something. If you read the reviews all the boards are a little different, speed, gybes, waves or blasting. They will all do the job, don't stress too much
