This mixup is easier to do than roll and better, just costs meter. I don’t think knife loops are hard but I can only think of maybe 1 other active one in America that can do them other than me so 🤷
Even off of the same routing (2C > 3X~C ... ) I prefer 214C setups, yeah. The reward on hit is worse since you cant get a jC starter, but the butterfly setup is reactable offline. I still use both. A nice bonus with 214C setups is you can use them to manage your meter and avoid heat, and you don't need to have your knife to do them in the first place. example: normal setup > 2C > 3X~C > 5C > 214C > jB(w) > 3C.
