New tool head v2 first thoughts review

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

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.

Oops n00bed and didn’t look around first New tool head v2 and Ninja Flex?
Just print the flexystruder guide and you should be good to go, no?

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.
