i think i would go with a special agent for heavy attitude,rapid fire,domination or agent depending on what you want pearl or solid on meds. and jolt for light  others to think about are thunderstruck solid,shift

Everyone is always chasing the EYE of the STORM

The DOOM is a pearl correct?  I hear from people who have tried both that the T-Road Pearl is stronger than a BWP and that's kind of their mid level ball.  Do you play on really dry conditions for your style?  In other words, are you having a hard time keeping the ball from overhooking in general?

It's possible that out where you would like to play there just isn't enough oil.  Maybe you have to get way in and look way out.  Out of the comfort zone yes but sometimes that's the way it is.  If you get in and swing the ball out, does it turn the corner?  You may not have the best ball reaction for your style maybe.  Are those the only two balls you have right now (pearl covers)?  Have you tried solids or pearl particles?

With slower ball speed, the Special Agent should handle any volume of oil but at the same time you will only bust it out when you are in the soup (but you will love it in those situations)...  Secret Agent is a smoother reacting Special Agent with a hybrid blend, depends on what you want.  I sold my Secret because it overlapped with my Special too much.
 
You mention Spit Fire, but you want a smooth arc.  I found the Spit Fire to be a bit snappy and later reaction than a similarly drilled Thunderstruck Solid.  They both handled the same oil and did the same thing essentially but I preferred the Thunderstruck's earlier hard arc reaction.  I don't know anything about the current Fire line except for the Spit Fire.  I tried it and didn't like it, but others prefer the Fire ones any day.  Another option here is the pearl Agent which should be stronger overall than a Thunderstruck but definitely a nice aggressive arc shape.  

On the light oil you mention Tropical Storm, and there have been debates over whether or not a Jolt/Jolt Pearl is more favorable to a Tropical Storm.  The Jolt has a smoother reacting cover.

In terms of drilling it is pretty individual.  If you take your current stuff into you pro shop and tell them what you are experiencing with those balls they should be able to recommend some different ideas in terms of layouts.

"When in doubt, pull out." - ESPN's Rob Stone

That is something to consider, what condition do you typically bowl on?  It kills me seeing these guys walk into a league that is playing on a THS with their 9 ball monster bags, and then switch from one high performance hook monster to another to another instead of making an adjustment with their feet or with their target, etc, and continue to do the same thing over and over again, unless I am bowling them, then I egg them on to try another ball in their bag b/c that might give them an even better look.

If you typically bowl on a house pattern, I would look into the T-Road Solid, and then maybe a Jolt.  This will get you through a majority of your league shots that you will come across, as well as a lot of the shots put out for state and local tournaments.  The only other thing that you may want would be an Ice Storm or another piece of plastic for your spares if you need it.
