What do the experts here think? I have a big brush rotation and I have been using a Simpsons Chubby 2 Synth for the past 6 months as a daily driver. I thought I better use my Semogue SOC Taj Resin Boar for some rotation and I found that the SOC barely held enough lather for a second pass. The lather simply dissipates in the time it take me to complete my first pass. It seemed to work well when I broke-it-in more than a year ago - but now, after a 6-month break, it's barely performing - and even shedding the odd hair which it did not do originally. The Chubby Synth on the other hand has given me fantastic lathers for two-passes and continues to do so. I am using the same soap (Vallobra Almond Shaving Soap Block) so that is consistent. Is this a case of a brush suffering (or sulking) from no use and therefore needing some break-in again? Or does the SOC just not like the Vallobra? Or is the Chubby just superior in this case? Anyone have any advice?
