Re: George Kollias here...
Whats up George? Its great to have you on this board.
I tried the demon drive as well, it was a really nice pedal, slightly heavier feel than axis and a little more powerful. One of the best double pedals you can buy, you can't tell a difference between the slave and master pedals. For two single pedals though, i'll stay with axis as well, still the best pedals out there in many ways.
I've got to get practicing, keep us updated on the new Nile album!
