I absolutely agree with the Forza, Primal Rage and Covert Revolt. Having a Covert Revolt, it is excellent when you have longer/heavier patterns yet is still smooth and controllable. Primal Rage is great when you need a lot of backend and the Forza is a great all around ball.
For THS, definitely consider the Venom Shock. That ball is versatile and will give you a lot of options on how to play the lanes. Below that, any of the Tribals would fill in on your medium-light patterns and then go to the Ascent if you need a ball for the desert. The Apex will be stronger than advertised however.
If you can still snag a Sigma Sting, pick one up. That is an awesome pearl that has a reputation of being a killer benchmark ball.
