Above is a link to the BJCP's, which is the Beer Judge Certification Program, style guidlines for Meads. It is the 1999 HTML version of Mead only and the 2nd link is the revision 2004 of all style (beer and mead) guidlines in PDF.
As far as selecting a Mead from each category I would say that for sweet meads Chaucers is probably the one I dig most. It also comes with "spice tea bags" to steep in it for a mulled effect. Chaucers may also be warmed with the spices for a nice cold evening drink.
For a "still" mead I would go with Redstone's Mountain Honey Wine(the traditional). It is made from Orange Blossom honey and still has some sweetness to it.
But if you go with a product from Redstone I would say that all of their products are excellent. They are probably the only company I would say that I have enjoyed all their products.
