Best coke I've seen or had was fully powder and a bump had me in control of everything around me for a while scarface style.
Recently I was meeting up with a guy and he's delaying me for 45 minutes, he gets to me and it's straight powder, it was pretty obvious he just went and got some inositol and sifted it through so in that case it would have been cool if it were rocked up a bit more than it was. I guess it depends on the circumstances, and where on the food chain you are, whether rock or powder is gonna be better. Has a lot to do with knowing your source and your source's tendencies. But as for saying cut and dry "This is rocked up so it's good!" that's just nonsense, there are a lot of factors to consider, nothing is that simple and as it's been said in this thread, when it comes down to it rock or powder means nothing.
