more advice, a drop B tuning is best if you have heavy gauge strings or string retainers to stop them flying back into your face and snapping and ripping your eye out and screaming "aaargh! dude! my eye! duuuuuude!"
something else about the drop b tuning, NEVER be tempted to use any of your fingers except your index finger because...
A) Playing a power chord with your pinky (if you were jumping 4 frets) is easy, but the chord will be in a wierd shape and be out of tune
B) Of you want to learn to Slipknot's level, they only use their index fingers for power chords. So basiclly, you can only play Disasterpiece with your index finger. not so easy now is it?
