Check out mine. We called it "Suicide" because it looked like you were shooting yourself in the face while you were tokin' up. Straight to the dome.
I would suggest just taking the drill bit route. Don't mess around with the torch because you will need a crazy amount of heat to melt a hole that won't come out as uniform as a drilled one. I used something that was very similar to this one. I've had a very high success rate with drilling glass bottles. I don't think I ever broke a piece (I did crack one though) and I've drilled probably 20 pieces. My suggestion is to do it in the sink with room temperature water running over the area that you are trying to drill. The water will keep it cool, lubricate the area a small amount, and keep glass dust from going into the air/your lungs. Try and stabilize the bit as best you can because movement will break your piece before anything else. If I remember correctly this piece was pretty easy to drill. Good luck! If you have any questions just ask.
