Soak the Brush - It's worth it!
I previously paid no mind to the whole "soak the brush in hot water" school of thought. I always just got it wet with really hot water before I lathered to shave. Last night I put the brush (I use a Rooney Type 3 Size 1 silvertip) in a bowl of steaming hot water for about 5-10 minutes prior to the shave, and I could FEEL the warmth from deep inside the brush while lathering. You don't get that effect by not soaking.
So, the brush itself acts as a mechanism for heating the lather as it goes on. I'd recommend it to anybody who doesn't go this route. It's well worth the time.
Just thought I'd share a personal experience.
Thanks for looking,
Ogie
