I have just gotten my first custom and it's a SFS, 55% 1B with 20% Gray.
I guess my two stocks from February of this year had gotten so light/faded, that a fresh 1B seemed shockingly black!! Other than that, the SFS instead of French completely dissappears and I'm EXPOSING HAIRLINE!! Cool as hell to be able to do that.
I did like, due to a combo of fade/Dermmatch, the fact that I didn't have to dye my side/back hair. With this 1B, I definitely had to. So, I'm wodering if a higher gray percentage would do it, or if a #2 color is the way to go?

Picture of a #2 next to a 1B would be great, as well as any 25% or 30% gray.

I actually like showing gray, although I got told 3 times in 4 days that I looked too young to have a 20 yr old kid!
