I am in a very similar situation to you and have ask the same question .
The majority of advice points to playing PCT at your home Game 1, then PON game 2 and PCT in game 3.
I guess the theory is, win the 1st game for sure, then your opponent will have to go all in in the 2nd game to assure that the series stays alive, then you can play game 3 all in, and the effect should be equal.
It's risky, however, if you lose game 1, you are in deep doo doo and might not recover anyhow.
