New tungsten nozzle on kickstarter, this time is tungsten carbide instead tungsten alloy as ddd material one (is it still existing ddd material?).
I have one tungsten one but still didnt have opportunity to try it yet (anibody did?, no news on this topic in the community).
Not sure what is happening with ddd material.
Though if you missed out on that, this one should be just as good, if not a fraction better
I’m taking this one too. I’m collecting esoteric nozzles this period 
. I hope to find some time in my schedule to try them . Time is day by day most valuable good. I was curious to have some feedback from ones who tried tungsten nozzles.
DDD’s should have been tungsten carbide for best wear resistance. The DDD shape was awful too, fat tip for the orifice. And the nozzle orifice on one of mine is visibly off-center. I didn’t bother trying mine because of the enormous back chamfer.
