Hey Dan,
The Rule and Animal are a little more "archy" but they are also designed to handle more oil. Based on your profile, I can see the Xception drilled properly for "arc" but like Icetink mentioned, it may overlap some. Since you already have the XXX, I'd say to drill some static weight out(you can also take the shine off to about a 1000 flat), even make it negative if necessary to help decrease the snap and then look into the Rule/Animal for a heavier oil condition.
Even though the Xception is a a longer ball, it really doesn't snap like some resins for me. The Goo cover seems to be in between a snappy resin and particle even with my slow speed and tilt. If you saw my Rule vids, you'd see a very strong arc and that was drilled for length and snap. Hope this helps some...
