Science Buddies: "Ask an Expert"

I am doing the project, What is the fastest way to cool a soda?
I would like to know any suggestions on which kind of soda to use.
Please don't look for any sites for me, I would just like people's honest opinion on which kind of soda to use.

Thanks

I don't think which exact kind of soda you use is very important so long as you use the same type for all of your tests so you don't introduce another variable.
