I might be getting a 7 string soon and I want to use it in Drop C for a couple of projects.

So what is the best tuning option?


(The string in brackets is unused)
Why don't you just use a downtuned 6 with a decent scale length?

And well yes, I'll enjoy the carpal tunnel and tendonitis, because trying to get one is clearly smarter than any word you have spoken thus far.
Why are you planning on buying a 7 string guitar if you're only planning on using six of the strings? If you were going to use a 7 string for the usual/generic drop-tuned metal chugs then you would probably go with ACGCFAD, or your second option (with the 7th string being a B.) If I understand your post correctly and you'd be leaving one string out, then there's no point in getting a 7 string. You'd be better off using the additional money to buy a 7 string to buy a nicer 6 string and use thicker gauge strings and a dropped tuning.
^ I think he's buying a 7 string anyway and just using 6 on some particular project
ProTone Pedals: Attack Overdrive
Fractal Audio: AxeFX 2
Engl: Fireball 60
Zilla: Fatboy 2x12
Carvin: DC700
Carvin: Vader 7
Schecter: KM-7 MKii
Schecter: Banshee 8 Passive
Jackson: DK2M
I'll be mainly using the 7 strings in standard tuning but will want it in Drop C for a couple of bits until I buy another 6 string.
