Experiment. "What is the best moassel," is really an unanswerable question . . . the closest correct answer is "what do you like?" Try different flavors/brands. You will find what you like. Check out reviews for other's opinions but remember that they are just that . . . opinions. In the end what is best is what you find you like. Smoke happy.
