I installed the fangtooth on my TAZ4 a couple of days ago and I made a thread for it. Being inattentive I threw this up in the general hardware forum but have a look at it. The nozzle has been a great upgrade for me. [Installation of Tool Head V2: Fangtooth (Hexagon) on TAZ4](https://forum.lulzbot.com/t/installation-of-tool-head-v2-fangtooth-hexagon-on-taz4/1334/1) > Even though I had hoped I could use flexible material with this (you can’t) new tool head Why not!? I may be super glad that I have an e3d-v6 coming after all. [edit] Oops n00bed and didn’t look around first [New tool head v2 and Ninja Flex?](https://forum.lulzbot.com/t/new-tool-head-v2-and-ninja-flex/1305/1) Just print the flexystruder guide and you should be good to go, no? [/edit] > I know the PEI bed is on the way as an individual component (and I’ll be snapping that up straightaway, trust me) Is it really that great of an upgrade? I currently use a ~20 line brim for ABS and can print parts that take up the entire bed space without warping issues but it would be sweet if I did’t have to. Is the PEI sheet much lighter than the glass bed? I have my TAZ4.5 printing at 175mm/s with the acceleration set at 2000–trying to get it to print beyond UM2–so the weight reduction in the y axis would be a bonus for me. --- _[View the full topic](https://forum.lulzbot.com/t/new-tool-head-v2-first-thoughts-review/1315)._
