Rusty w/ MMax 4600 .. 2s, 3s, or 4s?

[kulangflow]

I'm pretty sure that I'll go with an 8000mAh MaxAmps battery, but I need to figure out which voltage I'll be most happy with.

Background:

-My Rusty has the 4600kv motor and Anaconda tires.
-Drivetrain is already beefed up for power.
-I enjoy bashing, jumping, speed runs, and taking long walks on the beach.

Questions:

-Is 4s really okay even though CC says it's not?
-It seems like 3s with gearing options would be a good happy medium, but is it controllable at lower speeds? (ie no cogging, smooth)
-On that note, is 4s controllable at all?
-How about temp considerations?

I've searched through tons of threads and I'd really appreciate tailored info for my situation.

Many thanks in advance!
