When I get the extra enchant perk I was going to go with fire resist and one of these which would be better.
Thanks
The power of your enchants is based on your skill, perks, and whether you have fortify enchant effects going when you do the enchant. It has nothing to do with the power of the items you disenchant to learn the effect. So, keep that in mind.
In general, the armor fortification enchantment in Skyrim is pretty crappy, so I'd go with the health fortification given the choice between those two.
