. . you have trouble figuring out what else to drill.  I have a Sigma Tour, 65x5x40, and I literally have no need to carry anything else.  I have several tournaments coming up soon, and I really feel like I need to drill another ball or two, but everything I look at doing would be too much overlap or extreme to the point that it makes it a niche reaction, and I don't want to drill a ball on the off chance I may need it for a few frames.

I have the Greater Ozarks Open coming up in 2 weeks.  The Sigma handled both houses just fine last year, transition just pushed me a bit deeper.  I have a local sweeper coming up a couple weekends after that, but that's on a familiar shot.  Then I have Nationals first weekend of May, but the Sigma also handled everything from fresh to destroyed in Baton Rouge (wasn't able to go in 2013).  Then the weekend after that I have Swiss Trios here in town, the shot will be determined the week before the tournament, but this is a higher friction surface.  6 games first day, 6 games second day, so I'm fairly sure they'll go with a wetter shot to hold the transition at bay, but like I said, it's a higher friction surface, so everything plays drier than it's supposed to. 

I have no problem creating hook, and I can move as deep as I need to.  If I drill a ball to handle heavier oil, I'll most likely only use it to burn a shot for my Sigma, and I'm not really sure I'm going to see too much transition for me to handle.  I feel like I still need to drill something, but at the same time I don't see the need.  I probably wouldn't go more aggressive than a Primal Rage, and wouldn't go less than a Tribal.  Suggestions?
