I'm citing a situation that's happened to me several times during an actual match, but that doesn't matter (LO will just U-turn into Politoed as you switch out anyway, making your endeavor pointless). The crux of what I am saying is that you should not be switching Ninetales into Hurricane at all under common conditions. In your calcs, if rocks are up and Ninetales switches into Hurricane, it will die switching back in and Sun won't go up. You have to spin before bringing Ninetales in regardless of circumstance.
Also, misleading information; Ninetales lives a Specs Hurricane at full HP no matter what: 74.9% - 88.3% You can take a Specs Hurricane after Rocks with 120 So Def EVs, true (66.3% - 78.3%), but you could just as well die and lose your Ninetales for no reason.
Speaking of Tornadus-T, I don't know how you're beating him at all with this team. :/ The thing I can really think of is changing Forry back to Bronzong and turning Latias into Espeon to prevent rocks. Assuming you switch Lando into Garchomp, you shouldn't be any more vulnerable to Heatran than you were before.
EDIT: Missing the main point again. I'm saying don't change your spread just to switch into Hurricane after rocks when it's still risky and definitely don't switch into Hurricane at all if you can avoid it. Those 120 EVs cover a contingency that should not be happening over lowering the net damage Ninetales takes from Pokemon she commonly switches into/checks. This is explained in the Ninetales revamp thread
