this reminds me of an online fun quiz i took a long time ago that consisted of all the logos from all auto manufacturers. the trick was that you had to properly name the brand, but any wording was editted out. for example, all that existed for the Ford logo was the symbolic Blue Oval, Chevrolet Bowtie, Hyundai's crooked H, Subaru's stars, etc.
branding is extremely important for the non-pool player and pool player. i think the "casual observer/non-pool player" category would be able to identify very few things when it comes to pool: the 8 ball, 9 ball, maybe the Dufferin red maple leaf (however, they probably wouldn't be able to name Dufferin and might also just associate the leaf with Canada).
even a pool player may not recognize many of the brand names. if you were to blend out all the text in the Brunswick logo, the outline would be distinguishable to very few people. However, Ford's Blue Oval is recognized worldwide by many. i agree that Predator's cat logo stands out, so maybe they would be most recognizable.
