Cool rock riffs #1 - matt makaha

I have an instrumental version, and a newer vocal version of this song that I recently uploaded. Do you think I should go with the instrumental version or the vocal version?

Here’s the instrumental version:

Here’s the vocal version:

I kinda like the instrumental version better actually, especially from the second verse onward, because I put the melody up an octave higher, it sounds a little bit Satrianish when I do that. It seems to work a little better than the vocal version, but I'm not entirely sure....
