I always choose xp lamps. Like, lets say I saved 100 of them stupid frog tokens. (Yes, it's happened to all of us. : D ) And lets say I get 890 in this certain skill I'm working on per lamp. 100 X 890 = 89,000 xp : D Keep in mind, this is free and timeless xp. So let's say, you used it on prayer, or slayer, or runecrafting. Not only would it be faster than any of the normal ways, it's also free. =) Very good on prayer in my opinion. : D
