I don't know... C sounds pretty good
You have to understand that On and Off road requires a much different tread, especially if you ride spirited. There are hybrid all terrain tires out there, but not so much in the fat tire world right now. Even then they are a compromise as they don't excel as a single terrain tire does for its particular purpose.
You said that you ride mostly paved so that was the reason for my suggestion. I ride similarly and have swapped out for a more pavement oriented tread with great success on more than one occasion.... so have many others here. Sometimes I'm moving at 20mph and divert to off road to avoid a traffic jam without issue. When I had an off road tire I often found myself sliding on pavement, especially with aggressive braking and tight turns at speed. Not an issue anymore.
I'm sure the 4" factor plays a roll in your case, that's a lot of rubber on the road to begin with.
So though noise is a consideration... Traction, rolling resistance and even micro_vibrarions played a much bigger role in my decision.
As with any new/different tire... Feel it out and learn it's breaking point and you'll be fine.
Too bad they didn't have the tubes... That would have put you over $100 and gotten you free shipping.
So basically the tubes would have been free.
