Which brushes for Poly Scale?

I have been using Floquil and Diosol paints for 40 years. Will my presen brushes work with the new paints? I think they are sable brushes. Also, what number system constitutes a smaller brush?

My old small brushes were 00000 for small and #1 for large.

What ever worked with enamel will work with acrylics, I think. Here’s a good place to find out though.
