What Casting Investment are you using and why?

I’m using Satin Cast 20. I make rings to fit with 3D printing and so far (in Silver) I haven’t had to resize anything.

What are you all using and why? I just made this thread because I’m curious. I know a lot of people like Prestige and Plasticast so I wanted to hear why.

I switched over to R&R Ultravest with Bandust as I felt it was safer and have been very happy with the smoothness.
