Woah, wait, I just read your comment a couple posts up.
So when these things collide, the opposing forces basically rotate the Layers backward until the combination disassembles?
That seems extremely, extremely obvious in retrospect, but I really didn't think about it until just now. Well, I feel like an idiot, haha.
In that case, I would have serious concerns over part wear and manufacturing error. Plastic ARs, as mentioned in the last several posts, had problems with coming loose over time; if that's the case with Burst Layers, parts could become competitively useless extremely quickly if exposed to enough force. That, and if the diameter of a layer were increased or decreased during production by an incredibly miniscule amount, the pressure and friction it had with the Disk could increase or decrease dramatically, causing wide performance variations in the same part.
Think about legos (which is, on a base level, what we're dealing with here). When legos are new, they fit together much more tightly than when they have been used for a long while, and even when they're new, some lego bricks of the same kind can fit together much more tightly than others.
