A 7th Floor flavor disc used in a pipe is best used with lighter so you get the lowest temperature possible. Also, to slightly tap the flame on the flavor disc helps with a smoother hit. The lighter is about 600 degrees and you only need to get cannabis to 428 degrees to release all the cannabinoids.
You can use a torch every so often to really burn off the fats and lipids that will gather in the flavor disc from low-temperature dabs. Just remove the flavor disk and put it on a brick or concrete outside. Make sure there is nothing flammable and then burn the disc until it is brand new again.
