I don't think that the home or road component of it matters at all when you are talking about any of the big 3 (definately backe it would be huge, which is why wrapping this sumbitch up in 6 was so important- so he didn't have to go road/road in 2/6).
I think that you just go with whatever floats your boat rest wise.
Honestly, I have no opinion on that matter- would we rather Rocket and Pettite both go with extra rest by going 1,2 or give Pettite no extra rest and rocket 7 or 8 days of rest. Will it help Rocket to have an extra 3 days or will he get rusty. I personally think that I'd go AP then Rockett as Clemens seemed at his best in September after he missed the start on 10 days rest and I think he's breaking down, but I don't have a hard and fast opinion one way or another.
I doubt home/road plays into this, nor pressure into this, I think its Scraps decision on rest vs rust with Rocket
