7 string guitar & tunings in metal gernre (question)

[Dick Brucinson]

What are the most common tunings for 7string guitars in metal genre?
Is the regular tuning just with an additional low B the most often used tuning? I find this a bit boring actually.
Further ideas?
Thanks & best wishes,
Dick Brucinson

The most common ones are B standard (B E A D G B E) and Drop A (A E A D G B E).
