All good tips here. Though in regards to elemental weapons, it depends. If you are using a fast hitting weapon (dual blades, longsword, SnS, Lance, Bow, bowguns, IG) it will be best as elemental is a flat damage value applied per hit, rather than a percentage of the hit damage value. (At least as far as I understand). For heavy weapons (CB, SA, GS, hammer, hunting horn) raw damage is ideal.
All that being said…check out what the weapons look like, how easy they are to make, and use the one you like best, and later on you can adapt your build if you feel like optimizing.
