G'day All, I am a returning windsurfer after a 15 year break.... the last thing I sailed was a Bombora Zot!! (well tried to sail with mixed success

). I had the basics of water starting down fairly well, but like gybeing could never really pull it off on the Zot with what was at the time a reasonable weight rig.
I have been geting up to speed with the latest designs etc. but am wondering what size board I should be looking for. I have been looking at the boards around the 130litre mark. I am about 78kgs and 6ft. I would like to be able to a bit of everything, I used to sail at Dorans, NW bay, Southport, at the other usual spots around Lauderdale.
I would love some advice on matching rigs and boards etc to my body weight and forecast skill level, I guess I would consider my self to be a well advanced beginner looking to progress my sailing very quickly, thanks in advance Cheers VB
