the issue is that it's only a 5-6 second introduction, so i've gotta get in and get out, as quick as possible. i can't do sneaking as much as i'd like to. or balls rock, which would really fit my personal view of what a rogue is (cue ACDC music). i dunno if i can do it in 5 seconds, though.
i think triad's right - spanish as a sound that's instantly distinctive, regardless of how long i've got. it's also got a lot of cultural connotations (a la ben stiller's entrance in anchorman).
thanks for the commentary, guys, i'll let you know how it turns out.
