Duelund cast Pio Hybrid Copper/Silver or Rs series with Silver Bypass PIO

Hello.
So which one sounds better in the crossover - Jupiter Cu or Duelund RS?

grannyring do you know the Morel ET338? What do you think which capacitor is the best for this tweeter? 

grannyring4 Hi. ET338 is a dynamic tweeter with a good transfer of coppers plates.
But not enough air sound. I want more air in the music.

erik_squires4,  grannyring4 Thanks guys!
We tried the Mundorf Supreme classic, but we want even better. Tweeter requires  4.7uF so maybe we will try Jupiter Copper.
What do you think about Silent Wire LS wire? I was told that this wire gives speed transparency and air sound.

For 3-way (2x7", 5", 1") we need many meters of hook-up wire. Neotech silver with gold plating is too expensive here.
What do you think about DH Labs Wire Stranded Silver-Plated Continuous Crystal Copper? Which is better to use pure copper or silver-plated copper?

Hello @grannyring 
Did you tried bypass with a V-Cap CuTF 0.01uf?
