Pantone choice help


I'm looking for a deepest darkest almost-black brown, very specifically requested as such by the client. I'm not sure how well I trust my eyes to choose it from my little Pantone book by myself so looking for second opinions :)

I can't decide if 7533 is still too brown, or if 412 is actually black, or does it have a hint of brown? Or Black 5 is looking quite appealing as well.
I've been looking for too long now and they all look different every time I go back to them!

If it helps, I'm looking at signage, glossy paper bags and promo materials. The detail will be in lighter tones like 406/7 but I can settle on those once I've got the dark brown sorted.
