Anybody have an opinion on flat tops?
I love them. Have two: a D01 two-band and a D01 three band - for me the two-band is the way to go.
Do not go too big, I always 18-22 mm max, with 20 mm being the sweet spot. Loft about double the knot size.
Have one, a Shavemac DO1, and while it's a good brush, I won't get another flattop. It just doesn't seem to be as efficient in application, and the "feel" is off.
FWIW, I like bulbs the best.
