Diamond builds a fantastic product. They are well built tables, with a lot of great aspects about them. Diamond is a company that cares about the products that they build, and they support large tournaments.
However, the Artemis rubber is installed upside-down, which causes them to bank short. Regardless of that aspect, the tables are still quite nice, for a number of reasons. Because they are such nice tables, players will adapt to them, and disregard the known banking flaw.
There are a number of high-level pro players that absolutely hate the way that Diamond tables bank. I will not name them here, as it is not my place to do so. However, a number of them have voiced their opinion on Facebook, of the Diamond rail issues. Fact is, these same pro players win events on Diamond tables. Still doesn't mean they like the way the table plays..
Your rationale is flawed.
Have YOU ever played on a Diamond without a worsted woolen cloth installed on it?
