PotsFollow

What I'd like to know is quite simple: what pots do you use when raiding/doing heroics/soloing?

I've been somewhat confused lately as I get conflicting advice from everywhere, I have the healers telling me to use agility pots, another warrior telling me to use strength pots and the internet telling me to use Guru's Elixirs!
So I'd quite like some advice. I'm an alchemist so flasks aren't really a problem to make if needed (most people seem to say that they are overkill, though), also it seem like fortitude is the only way to go when taking guardian elixirs, unless using flasks.

Thanks for your help.
