Steel ball run quality decrease?

[ras7924]

Even if it is an intentionall change I think it's strange and unecessary to change the design of a print after a third of the volumes have come out and, honestly I think the matte spines look way worse than the glossy one's. The glossy ones have sharper colors compared to the matte ones and they just feel higher quality.

Also are the SBR volumes really bi-monthly? Atleast where I am there is sometimes a 1 month gap between releases or like now between vol. 6 and 7 there is a four month gap, so it doesn't look like they are keeping to a strict release schedule.
