If you use maces, just keep the iron one until you can make the Plains-tier mace. If you use swords, the silver sword is decent until you can get the Plains one. The only really good weapon from Mountains is the Draugr bow. I'm sure some will take issue with that last statement, but it's mostly true. Hold on to Frostner though. It's usable for fighting Yagluth and all through the Mistlands.
