I was kind of forced into dripping when the mega cartos kept failing in performance and my flavors went south so soon after filling a new one. I was amazed at the consistency and fullness of flavor that dripping affords but I really missed the feel of a flat tip. Someone mentioned that they made flat tip carts for the 901, which also fits the 510 and Ego. I ordered a package of 5 for $3.99 from Good Prophets and found, with a little modification, they make a perfect little flat drip tip! I popped the end off of the mouth piece, cut off about 1/3 of the end that fits on the atty so it wouldn't scorch and used hubby's Dremel to drill a small hole through the center of the barrel. Works like a charm! In fact, it seems to add more flavor due to the concentration of the vapor through a smaller opening. It makes the draw a little less airy which is another added plus IMO. I haven't had any problems with liquid getting on the outside of the mouth piece, even though it is a smaller area to hit. I'm really enjoying it and just wanted to share.
