Hello! I ordered a Dingwall NG2 5 Seca blue, and it should arrive in sep/oct. So here's a few questions for the waiting time.

Im going for some lower tunings for e.x drop C with low G (GCGCF)
I was thinking about the kalium strings steel set "158 118 90 67 51"
Will it fit in to the bridge and nut without any modifications? And also taking advice is the 158-51set fine for this tuning.
Also i was thinking to buy the Gator GPE-Bass-TSA case. I've heard it should fit in it. Any confirmations about it? ( Link for the case:

Thanks for your replies.
