Best times of year for the Ginza shops?

[Madladam]

Just recently missed JAV Yuuri Minase at Club, but still saw lots of great girls rostered at Empire, luckily including the incredible J Mio. French Chloe said she’ll be on vacation a couple months around this July. I’ve heard J Hibiki is coming back in October. Are there times of year like maybe winter when the roster tends to take a hit in quality, or are there usually a variety of high quality girls(in addition to the girls already mentioned, like other JAV girls and girls with stars next to name, etc) to see year round?

Edit:
For anybody else who might find it helpful, upon reviewing past posts about girls rostered there seem to nearly always be at least a few good options. Harder to figure out how often JAV or starred girls are rostered though. Just figured I'd ask here since in my experience with FKK Sharks in Darmstadt, late Dec to early Jan and around Orthodox Easter are warned as being times with fewer good rostered options. Wasn't sure if any similar pattern might apply in Sydney, but apparently not.
