I like to have 2 7's one tuned in B standard and on tuned in B flat. as far as brutal goes (i ahte that term) IMO that is in the hands of the players and the riffs they are playing. I like to use my B standard 7 as my main "overall" guitar so I play lots of 6 string songs on it as well.
Unfortunately until I get my Rico all I have at the moment is a 7620 in Bflat
