Looking for scales

What would be some good scales to use for a metalcore/metal band? I'm looking for some new scales to learn to apply to our song writing but I can't seem to find any that really fit the sound I want. We sound like a mix of Killswitch Engage, Mudvayne, and Slipknot with the groove of old style Korn. That's the best description I can think of at the moment. Any help would be greatly appreciated. Thanks.

I'm so out of the loop with all of the new bands out there but I remember using a lot of the Whole diminished scales.

E Whole Diminished

E - F# - G - A - Bb - C - C# - D# - E

Most of the bands you're influenced by use a lot of altered tunings to create their sound from diads played at a single fret location.
Take Drop C tuning for example: Strings Low to High = C-G-C-F-A-D. This tuning creates an interval pattern of a 5th, 4th, 4th, 3rd and 4th. These altered interval patterns make many scale patterns have to be altered by their original fingering placement by intervals, created from standard tuning.
The Whole tone scale is ideal because it is a 6 tone scale of which any note can play as the tonic. There are basically only two scales you can create with it. One will contain the notes F-G-A-B-C#-D# and the other will contain the notes F#-G#-A#-C-D-E.
Another scale you can experiment with are the Harmonic minor/Major scales.
Good luck..............
