The joists sound fine and are pretty much what most of them were done with I believe. Personally, I would nail the decking and predrill the ends to avoid splitting. A nail gun is a godsend in this application. Galvanised or stainless steel nails are what you will have to use as plain steel will rust pretty fast I believe. 50mm is the go I think (check with others), depending of course on your decking's thickness. If nailgun-ing them, I also think the nail heads should "just" break the surface NOT go right in. Decking nails have a rounded over head. Do you know the species of hardwood and is it decking timber or flooring? Pics of the home if you have any please
