Hello, I need advice from the community. I’m a new owner of an Ender 6 and I would like to replace the heat break but can’t find the exact reference. Please would someone point me to the right replacement part? Is it MK7 or MK8 or else?

I’m also open to upgrade/purchase a new hot-end with the same dimension. Same dimensions, because I won’t mod the BLTouch position. 
I saw that some hot-ends do not require the heat break part anymore… Just bowden tube to insert and voilà.
Let me know what would be your first choice hot-end.

I think, it would be great to have all hot-end specs stored somewhere in case someone like me (total nooby) can easily find the replacement parts.

Thank you in advance for you help.
