I'm not much on understanding clock layouts, but I think my Emerald and Gold Nugget are close to 1:30 and I probably will drill my Uranium the same. Nothing wrong with all of the balls having the same drilling as long as you have different cores and covers. For example, my Emerald and Nugget have the same layout and both hook about the same number of boards with the difference being that the Emerald goes a bit longer than the Nugget. Just like this past Tuesday, I started with the Nugget and then halfway thru the second game it started hooking a bit early, so I finished with the Emerald. The Emerald went a bit further than the Nugget and gave me the same looks in the pocket that the Nugget was giving me before the lanes changed and made it start hooking a bit early.
