Thanks for the review.
Funny, I actually like Salix because it *doesn't* go dark, but stays bluer. Other than the amazing shading DRBB gives, I didn't really care for it. People kept talking about what a great ink it is, but I see that in your review it ends up as the same washy blue-grey color that I got.
For an IG blue-black ink that really goes dark (not washy) I prefer Ackerman #10, followed by FPN member Pharmacist's Urkundentinte. (I can't compare ESSRI, since I have not ever tried that).
