Out of curiosity, what is unique about the disc hubs in those discotek cases?
I would normally think that the ‘soft’ plastic used in most BR cases would avoid any potential damage to the PC disc.
On reflection, I guess that’s a particular advantage of the long-arm-pair that Amaray use (or the joined-tripod types).
But I have cases with a vast array of different hub designs. Off the top of my head, there are 4-arrow (and 4-blank) clips,5-arrow versions, ones that have the arms twist, ones that have a single button clip in a circle,.. Pretty endless variations.
Any concern is usually that the design causes some deformation of the inlay (the lever action or void), that the small details cause result in more fragile weaknesses, or that it’s particularly resistant to releasing the disc.
