Things like System of a down and early Deftones are played in Drop-C# so to play it with a B string I'd have to move the 5th chords really quickly and higher up. Got a little too difficult with some riffs so just used my Les Paul instead. Korn, Fear Factory and Orgy songs were easier though (I spent a lot of time rocking out when I was a teenager).

As far as playing with the extra string, you just have to practice. After about a week of playing it it'll feel normal and it's not too much different, just remember to mute it when playing chords etc.

The best thing to do is play them both and see if you find it comfortable or not. If not, you'll never get on with it. I'd have another, but thats me...
