What would you do? Tires vs. days vs. championship, have A6, A7, free to mount Options

Figured I'd throw this one out if anybody has an opinion.

Right now I have 2 AX days (16 runs) on my A6's. They still feel great. I also
have new A7's in the basement, and since I have 3-piece wheels, mounting is free
except for my time.

I compete for the championship in NCR PCA, there are 6 events and 4 completed.
I won 3, so winning either of last 2 locks it up. Last event is october which can suck
for weather (914 is not competitive in rain next to modern cars IME). But coming
up next is a 2-day (counts for NCR and also PCA Zone 1).

Would you:
a) Just use the A6 for 2 more days
b) Use the new A7 for next event then pop A6 back on
c) Flip A6 on the rims
d) other
