Speaking of bands "consistency", I have a pretty small OEM bands collection (less than 20), and these are the SB I purchaised in 2021: Delft Blue, Mallard Green, Pollen and Spearmint.
I do have noticed that they feel very different from each other: Pollen and Spearmint are pretty soft, velvety, heavy on the wrist, while Delft and Mallard are light, stiff, not velvety to the touch. I don't know if that depends of the production year (Pollen is older, Mallard is the newest collection) or, more likely, to the "tone": lighter colours feels softer and overall nicer, that's the pattern I've noticed. The white SB I received with my silver SS S5 is soft and velvety as well.
I'd like to ask if someone else has noticed this, and if some of the new, darker bands (like deep navy) feels the same way compared to some of the new light shades (like cantaloupe).
I do prefer the feel of the light colours, and it's a shame because I really like the deep, darker shades too. They just don't feel just as nice on the wrist, I don't know why.
