Has anyone noticed a difference in the STF fibre over the years?
My first was a 25mm from RV, circa 2013. Springy for sure and in no way would I mistake its behavior for natural hair. I bought an RV 23mm a year later and that was even more springy. Within days, I sold it to a friend who liked the handle and color.
Late January 2022, I received a 23mm STF made by Rudy and the fibre feels a LOT softer. Even with a loft of 50mm, it needs just a little more pressure (versus badger) to splay. My 25mm has a taller loft of about 54 or 55mm, but is far more resistant to splay. I also noticed that the older brush's fiber feels more "plasticky" (for lack of a better word) than the new one's. Am unsure if this is just aging/wear and tear, or if it is how the fibre from almost a decade ago really feels.
I've heard about STF v1 and v2. Others have stated that Muhle have refuted such claims, saying they've made no changes to the material. Anyone here with older and newer STF brushes? Has your experience been similar to mine in any way?
(The old brush still works, but am now curious if the newer 25mm knots are better.)
