AGCFAD (mastodon/neurosis tuning)
I've used that tuning a half step up to play 7 string stuff on my 6 string.
I usually stay around standard or a half step down, and I have an old Ibanez I keep in like drop A or B for when I want to play stuff like Slipknot.
I haven't had a playable 7 in years, but when I did I kept it a half step down since that's what I'm used to on my sixes.
