Pre-War Fat Handle Tech / Personna (1) / MWF / Old Spice -- went with a cold water shave... MWF+mild razor+cold water = a lot of clogging. I've had good cold water shaves with other soaps and razors, but the cold water congealed the MWF and kept it from rinsing from the razor. Frustrated, I made the rookie mistake of adding pressure... I know, dumb, dumb, dumb. Still got the great MWF post-shave feel, albeit with a touch of razor burn. I'm not giving up--I'll give this combination a second go Monday with warm water.
