Name character after random object or implement which describes their personality and/or appearance. These tend to be easier to remember, whereas names with extra vowels and the like are always hard to keep in mind. If I typo while furiously hammering out "rescue eerreekah" ten times, and you die, it's all on you. Yes, exotic is neat, it also makes things hard in tense situations, in the end, I'd opt for practicality with the syntax.
