I am level 33 and just got done with Kali's FF; now on to Broken Valley for the final time.

Should I load up the sword with its enchantments or turn it over to Hermosa in exchange for the experience?

I am not a melee fighter by trade, but a ranger/mage primarily. I have a good deal of trouble with Raze and find some melee skills helpful there. I have to go back to Raze's and get him.

Can I load up the sword with enchantments and then give it up later?
