Marijuana on Shrooms?

So first/last time i did shrooms, i did not bother blazing because i wanted to experience the whole shrooms experience by itself. This time (in 2 hours) I am taking 2x the dose, aswell as picking up 2g of some nice Trainwreck. My question is, when should i smoke for the most enjoyable experience possible? before i dose, peak, after i come down? etc..
