Around 85 reviews on Amazon for this tip but a very small percentage (around 10% are USA reviews, some positive, some quite non-positive). Maybe this is a European or Asian market tip?Same here. I've known about Royal Oak tips for decades and during that time I have played pool all over the country, and have read a lot of forums, and I have yet to ever even hear of somebody that uses them, much less meet anybody who does. I wonder if they are just popular in some small region of the country or something because you would think somebody has to be buying them for them to stick around for so many decades.
