<snip>Biggest con for me is the backbone. I haven't used a synthetic brush that excelled at face lathering yet because of a lack of backbone.
However, I hear the Muhle synthetics have more backbone than other synthetics.
My previous favorite synth, an Ever-Ready, lacked back-bone, yet that didn't deter it from being a lather machine and I only face lathered with it. My Muhle has perfect backbone for face lathering and painting.
