2 things today I really don't like Lab Blues. I got these in a sampler PIF, and they are the ones with the arrows on the blade in the holder with no wrapper, so they might be the Personna barber blades, and technically not the blues. Either way, not a good shave today. Really bad tugging, some skipping, and they just didn't feel like they were cutting anything. Didn't like them in my Popular or 37c. They were acceptable, but not great in my Fatboy, so I thought maybe my technique had improved. Tried them in the R4 today and I still don't like them... I may have a new favorite face lathering brush. I got an Omega S brush in a PIF. It seemed a little soft at first and I felt like I had trouble loading it. Today went much better, it loaded up great and seemed to produce better lather than I've had since I stopped head lathering my soaps.
