let me just throw the proverbial spanner in the works here .i my self have been a cold water shaver since i started shaving many many years ago . now in my time i have found that some soaps like a cold water shave and some just give me a bad shave .
and i put it down to what the soap was made for like proraso if you read up on it it clearly says use warm water . where as the soap i find a great soap at the moment mitchells wool fat i find lathers better and shaves better with cold water. also add into the mix the multitude of blades and the way they all shave i find a good blade like persona gives me a great shave yet a over sharp feather well lets just say it wasnt great .
so in summing up do what makes you comfy as there will be others that dont agree .
