Molly and Mary blowing at a concert

So here the situation, I have a concert im going to soon and have about 140mg of M, weed, and like a gram of blow.

What order do I consume these in for maximum enjoyment? I heard doing some Coke when you take the M is a good idea, and then I'll just re up the Coke throughout the night.

The Coke is 80% purity if that matters
