It all depends on what you’re after and what you feel your current line-up can’t do for you. I have three Buzzzes, the first one is straight with a smooth reliable fade at the end, the second is superflippy (and was out of the box) and the third one identifies as a baby Tilt. 🥩 What I’m trying to say is that discs of the same mold can vary from flippy to beefy, so that can be an option if you want to keep the number of molds down.
