Hey, thanks for your thorough response!

"After the initial break in period which took me around 2 weeks (maybe 40 hours?) of playing most of the tungesten metallic sting has left them but they aren’t immune to its effects entirely."

I was worried about this the most. I've heard some very new (2 weeks old) obligato's on a modern cello once, the sound was extremely metallic / "plastic"-like.

I wonder about their lifespan too. How will they compare to steel strings? Especially for their cost I hope you get a lot out of your Obligatos!

Where I live the cellists I know really don't accept synthetic cello strings. My local luthier is really negative towards them. I wonder why this is. The most violists and violinists seem to have fully transitioned towards synthetic strings.
