Since I don't have a lot of money to spend, maybe I would be better off getting something to fill the hole in my arsenal for dry lanes, and to be used as a spare ball as well.  I should be able to do this with a stronger ball than you might think, because I don't have a lot of revs.  Here are some of the balls I was thinking of as possibilities:

Desert Heat
Black Ice
Ice
Vibe


Those are just a few that I came up with off the top of my head, but I'm open to suggestions.  Maybe a Red Pin ZC?  I dunno!
