I have worked in the construction industry for about 25 yrs. I have worked with rough sawn, planed all round, seasoned, unseasoned, recycled, pressure treated and various mixed combinations of all mentioned.
In my experience if you set all your top edges level at assembly there should be little effect on the level of your decking over time. Your construction method is one I would only use if there is significant reason to do so.
Using Australian terminology we have joists and bearers. What you call stringers I imagine are our joists, this is what the decking nails to. What you call a hanger we call bearers - the joist are held up by these. Cutting joists between bearers would typically only be done if there is limited ground clearance or if you wanted the under side to be flat for fixing a ceiling too.
In my humble opinion you would have a much stronger deck if your joists / stringers ran over top of your bearers / hangers. Then all you do is either pack the joists level or the preferred method is to notch a little out of the joists / stringers so they are all level across the top. Any shrinkage or movement will have minimal impact on your decking.
If you you stick with your current method I would suggest a smaller metal bracket that does not need to be bent over the top of your timber or trim it with tin snips so as to avoid other lumps and bumps that will effect your decking.
Bearer sizes typically used in Australia are 4 x 3 and will span 4 to 6 feet depending on stress grade of timber and frequency of bearers. If you want a larger span between points of support then larger timber would be used.
