If I'm ever shopping for a new drip tip, the first thing I ask myself is "Is the opening of this tip wide enough to actually drip juice through?" (regardless of how cool it looks). If the answer is no, I look for a better tip. Nothing wrong with removing the tip to drip I guess, it's just an unnecessary inconvenience.
I def prefer metal drip tips with a 'wide mouth' if I plan to drip. Anything less can be a hassle.
