First Benchy printed with Bambu Lab X1 & CHT Nozzle

Has anyone tried the original Bondtech with copper and vanadium steel Nozzle with ASA from Extrudr?

I had good results with the original 0.4 Nozzle from Bambu Lab with this material. Ventilation had to be down to max 40%.

With the new Nozzle in 0.4 I can lower the temperature, increase ventilation, no matter what I do the result looks very poor.
