I use Proraso in the white tub, and I've noticed that I get the best lather by not adding more water than what the bristles of my Kent B2 hold after most of the water being gently squeezed out. I'm currently bowl lathering, by the way. If I add more water--as one sees on instructional videos--I find the lather too thin. The water where I live is very soft. Is softness of the water a big factor in lathering?
