Help needed with a Metalcore-like Song

[patriot2011]

Hello. I was wondering if anyone could help me with a metalcore-style song that I'm writing. I have completed the intro melody and the main verse, but I'm having some trouble with the chorus section... I can't seem to come up with a soft sounding melody to go over my rhythm. The bands that influence me (ATR, AILD, BFMV) use heavy chords and melodic melodies in their verses 9 times out of 10, but usually use softer chords and quieter melodies in their choruses. I guess I'm just stuck in "heavy mode" . The attachment is a PowerTab of what I've done so far, and the big question-marked sections are what I'm having trouble with. Any suggestions?

P.S.: I'm not asking for someone to write it for me, I'm just asking for ideas, scales, and/or patterns... Also: if you don't have powertab, the main rhythm is tabbed below...
