Well, you're partially correct in that it is a different mold.
That would indicate a different manufacturer. I wonder if they cost more???
Chuck, you're not supposed to notice such trivial details. Now you're an artist already?
What's important here is that they didn't raise the price......right?
If you're going to get serious about bumpers you need to get closer to the source.
These things are ridiculously cheap when bought in qty. and you know where to look.
Here's a clue. These are an industry standard item, they aren't made specifically for pool cues.
The billiard market was an afterthought, still is.
You guys already deal with the alternate sources. Search 'rubber bumper' next time you're there.
I got lucky, I never have to buy another bumper again unless I want to.
The local town/village was host to a Mohawk Rubber plant at one time, some buds worked there.
They told me that they run a bumper exactly like what I use on my cues. We talked.
Here's what really got my attention; they could run them in whatever durometer I wanted.
One of the reasons that butt-caps explode is because the bumper is too soft.
Compress it and it has no where to go but out, sideways. Good-bye butt-cap.
Start raising the durometer rating of the rubber and the bumper doesn't compress as readily.
To a small degree, you can tune the hit of a cue by the durometer of the bumper.
Anyway, I had them run some extra sheets when they next ran bumpers in various D-ratings.
I'm set for life and all it cost me was a case or two of beer.
