Moondays,
From the looks of your profile you do real well with that DZ! I would think that the Charcoal should match up very well. Pick your favorite drill and then tune it to your tastes by adjusting the cover, it's very tunable. It would follow that the Red should match up well for the mediums.
My self, for the drier conditions I like a weak drilled, shined up Green Gargoyle. You may have a little too much hand for that. Visionary has a ball slated to come out for the drier conditions but have wound up being a little too busy after Bowl Expo to concentrate on that just yet. Should be soon though.
Other than that, unless your looking for a heavier oil ball you should be set. I'm not sure what the status of Visionary's spare ball situation is at the moment. The first ball they sub'd out was their clear Gargoyle and it seems to have been a problem for them with quality control. (They are very picky.) The glow and the red Amulet are out of production now, so time will tell.
Hope this helps a little!
Pye
