I notice they come in ultra light, light and medium but on the PRESTO sight they mention that you should use SANDPAPER on the strings where you bow...

The ones we have which Presto I believe makes to a design I developed for JR Music is a steel string like a Flexocor. I only have the light gauge but we did develop a medium gauge. I re-termed them as Regular and 'Firm' I believe as the Lights feel normal and just about the same gauge thickness. The Mediums are just stiffer. I have the proto-type medium set on a bass at home. I only carry the ones they call light.

Unfortunately, JR Music is using the exact same name to sell both styles of strings hence the confusion. Contact them for more information if you need.
