What do you prefer?

Ao telefone com o S. sobre uma amostra que lhe mandei.

S: What is this sample you sent me?
Eu: You remember that when we went to the factory they were producing the same quality but with a thinner yarn. This sample is the first trial after adjusting the machine to a thicker yarn.
S: What do you prefer?
Eu: I prefer as the original sample, ours is too soft.
S: What do you prefer? Thick or thin?
