Grey Inks or Greywash

Hey Guys,

Ive seen allot of post about greywash but not many on Grey Inks. I know both are used in black and grey and sometimes even used together.
Wanted to see what you guys think about these and which you personally prefer using.
I feel like the greywash fades more than the grey ink which can be good in some cases such as potraits but some pieces look pretty dope with the saturated grey tones.

I allready have dynamic triple black that I can use for my darkest tones and eternal White for highlights and such. I was looking into getting another black such as talens to create my lighter greywash tones. Or just getting a nice set of grey inks and just dilute the triple black more if needed for greywash.

I use greywash sets....mainly because the darkness of the greywsh is consistant every time...I have found that mixing your own greywash from black and adding water can cause inconsistant shades, ....shades can change if you accidently put one and a bit drops of black in the cup instead of one drop, and you have to ensure that you add the same amount of water to that drop, and use the same size ink cup every time, it just gets a little confusing, whereas you can just go to your ink cupboard and select what shade of greywash you want, and it's the same every time, but having said that, I use the drop of black and add white to get different shades of grey, but the same problem occurs...remembering how many drops of black or white I used to make a shade.
