No modifications needed to put the Intercontinental #66 rails with a K55 profile on Gold Crown 1 - 3's (I've never tried them on 4 or 5's). The Artemis rails are the same rails as a Diamond Pro-Am. If you cut the rail angles at 141 degrees on the corners they will be the same angle as the Pro-Am also. (They are not black rails on a Pro-Am either, I can post pics of the whole process from start to finish). I did also use the Simonis 860HR because I live in Florida where the humidity is high. Also 7' Diamond tables with Simonis 860 play fine as long as they are done correctly.
The part that makes the GC play better than the Diamond is that the GC 1 & 2 tables have a much better constructed base and weigh a few more hundred pounds for stability (My GC 1 = 1340 lbs). So I guess you could say that I have a Brunswick / Diamond hybrid actually.
Concerning this changing or making a poor stroke better, that's a fantasy.... If your stroke is not any good my table will make you cry. I started being a table mechanic, managing and building pool rooms in 1984 and even made the cover of P & B Mag in September 1999 for building one of the top 10 upscale rooms in the USA. I am a very well respected player and building contractor that has built several parts of Disney World, Universal Studios, Sea World, 4 Hard Rock Hotels, 2 Planet Hollywood Nightclubs, 14 major Hospitals, etc.... (the list could go on for weeks and I am good enough at building that I retired at age 45).
