I have tried both 2C I and E a couple times in the past 2 years. They are definitely fun, and worth a try. 2C I is like a combo of acid and E. You get a body high in the beginning, and it feels more like rolling, but if you smoke, that will bring out more of an acid trip. 2C E is more of a visual high, but it kind of plays with your mind like mushrooms. If you can, avoid blowing either of these up your nose because it is one of the worst burns possible. They make liquid forms of both, and I would say that this is the best way to go. You don't ever have to taste it, and it lasts the longest.
