Yes, the shave process is an individual thing.
If i was forced to use one soap, one brush and one razor "no matter the quality" the shave would soon become a boring chore..
A big part of the enjoyment for me is choosing from a very large variety of tools in my arsenal.
I admit that i have spoiled myself with a very large collection of razors, straights, DE's, blades, brushes which are all used.
The choosing of the shave brush is an additional increment of the enjoyment for me. Yes agreed,.... to each his own.......
