I'm having a bit of trouble finding decent samples of Vanishing Point and "Set Your Controls", but from what I'm found they seem to have potential.  
I think I can safely say that Viking Metal isn't really my kind of music, the vocals just don't do it for me.  Amon Amarth, Battlelore, and Blind Guardian are just simply too dark in nature.  Also, "Exploration of Space" just doesn't feel interesting to me.
"The Adventure" is a decent song though, and Liquid Tension Experiment has some catchy stuff.  
I almost didn't look up Dragonforce, but I'm glad I did, because some of my favorite stuff so far I found by them.  I think my favorite find so far out of these suggestions is "Evening Star" by Dragonforce.  It's just the kind of thing I'm looking for.
I haven't finalized a decision yet, but I'm liking that song at the moment.  Thank you everyone for your suggestions thus far!
