Thread: Bulb vs Fan??????

Just wondering if someone can tell the functional difference between bulb and fan type brushes. I'm looking to spend some money on a higher end brush ($180 max and leaning towards a Thater) and want to make sure that I get something that suites my needs. I use harder soaps almost exclusively (C and E, MWF thinking about adding tabac to the rotation) and switch between lathering in a bowl and face lathering depending on how much time a actually have. My current brush is EJ pure badger (21mm/ 53mm) and although it is functional there is alot of room for improvement.

Also anyone know of a good tallow soap, maybe something with lanolin I'm big fan of the scent of the crabtree and evelyn sienna (described as a masculine blend of leather, citrus and spice with a hint of fire and herbs) and would prefer something with a similar smell.

Any input would be greatly appreciated.

Cheers
