mate I'm around the same weight ....give or take a couple of kilo lighter!

102kg and I have a Nash 11 6' which I use for flatwater paddling mainly ,and it's a great board .
I must admit I haven't tryed anyother brands ,but I'm more than happy with this board.
I got it off the guys at windsurfnsnow ,and I'm pretty sure they would have other nash boards for sale there in Sydney (northern beaches).
