I found dual wield and 1 hand shield to be very solid.
DW for aoe damage, flurry for dps, or sparks for extra protection (causes miss chance, pairs with blinding flashes nicely).
1 hand shield is awesome for bosses (debuffs) or when you need the better block.
My armor is full medium, health and stamina enchants.
Now I am raising 2h and bow, same armor. I really just haven't gotten into bow, but I will stick with it a bit more. 2h seems nice though.
The only thing I missed with DW and 1HS was range although flying blade in the DW line is not bad.
