What are you even talking about? I'm not sure even you know.
If they wanted to copy Brunswick why stop at the cushions which nobody can even see while hidden under cloth? Why not use Formica rails, metal pocket castings, multiple piece long rails, etc???
I like how you pick and chose what you are willing to answer, quit cherry picking and answer the rest please. Explain the above, then maybe, just maybe your cushion beliefs can gain some traction.
I suppose you believe that any cue manufacturer that has points and veneers are copying Titlist?
