Without a user profile and your bowling stats, it's tough to make a good recommendation. What is your speed and revs?
I might also ask what type of reaction you want on the THS? Skid flip? Strong Roll?
Generically, the Gamebreaker, Mystic, Solid LevRG, Raw Hammer Anger, or Horizon Solid might be good choices.
For more performance, perhaps the NSane LevRG, Momentum, BW Bite, Complete NV, etc. might be options.
We need more info. from you before giving you accurate advice, though.
