Have you tried any? Which are the best seamless balls?
As far as i know all seamless balls come from only 1 chinese factory. I have seen the process and doubt that they make them different for individual clients other than the printing .
There are a lot of myths about re balls, seamless or not.
One of my clubs just invested in DHS 40+ 3 stars blah blah balls and some players think they are the best since sliced bread and some others think they are crap and always sound like they were cracked.
I took a couple home and compared them with 3 other brands of various specs and price.
All of them were the same diameter 40.15mm (calipers)
All of them were the same weight, 2.55 gr (tripple beam scales)
All of them had virtually identical bounce characteristic ( eye-ometer)
and last but not least:
All of them were not round and wobbled when spun. 🤣
P.S, In my other club we use Stag seamless and they are "OK"
