If you jump into the tire review thread, theres a guy whos used those and some MXM4's.

The A/S have better wet traction, the MXM4's have better dry traction.

I wouldn't touch that firestone tire, my vote goes to the pirelli or the michelin.

If the Michelin is the least expensive option, go for it.
