Artemis on GC is just a bad idea imo.
Let's ask Mark.
The contact area grabs too much. No matter what you do.
OK when the cloth is still new.
Not when it gets old.
SuperSpeed banks just as well when the cloth wears out.
See what iusedtoberich says... I don't particularly care whether the banking is perfect over the life of the cloth.. As long as the table plays as close as possible to the DCC Diamonds. I haven't seen consistent opinions that the Artemis rails on Gold Crowns naturally sit higher or lower than they do on a Diamond, so it seems to me they would play fairly close. If that means that the Diamonds bank different when the cloth is worn than when new, then I am fine with that.
Given that I have had my foot on the throat of the few pros I have played in One Pocket at DCC, and let them get away in part due to lack of quality bank practice, I just wanted to come to Derby with a "feel for the banking zone", as it applies to the rails on the Diamonds. I haven't seen a strong case that Superspeeds bank extremely close to Diamonds, so once we get to that point, the argument now becomes, "If I put Artemis on instead, will it bank closer to a Diamond, or will it bank jacked up?
I haven't seen a strong case that it will be bank jacked up, and I have seen multiple opinions from people that have put on Artemis rails with no subrail modification, and been extremely happy with how the table plays. Given that I have not seen a super strong case that Gold Crowns with Artemis rails bank poorly, then I am fine with being the guineau pig and making up my own mind. If it doesn't work out and the table banks noticeably poorly, I will report my results, and I will just try again with Superspeeds.
Remember: Artemis is a German product, and these rails are significantly cheaper to get here than in the states. So, it's not like I am breaking the bank by giving them a try.
