Lots to consider without seeing you bowl...

The Throttle is a pretty aggressive particle ball meaning that it wants to hook early and even as opposed to lots of skid and a big snap at the end.  Many people actually make the mistake of throwing them on too little oil.  The ball hooks early, but loses it's rotation early and rolls out and hits very weak.  A simple test for this is to get the proshop to apply a light coat of polish.  If you get a more desired result, either keep the ball polished or buy something weaker and save the Throttle (dulled again with Scotch Brite) for heavy oil.

If you problem gets worse, you are actually bowling on more oil than your style and/or the ball was intended for.  Keep in mind that nothing will hook on a flood.  Throwing the ball hard on heavy oil is hard to do unless you turn the ball a lot.  To increase hook, your normal adjustments are to slow down, move right (assuming right handed) to where there is more dry, or sand your ball to a lower grit.  If the Throttle really isn't enough ball for what you see, you're not going to buy much more hook.  Some of the newer releases will handle a bit more oil, but probably not enough to justify another purchase.  If you're not comfortable throwing slower or moving a lot, get the ball "sanded" (in general, use Scotch Brite, not sandpaper on particles) to a lower grit.  Green Scotch Brite is 600 grit.  If you really need more (rare), burgundy Scotch Brite is 320.  Keep in mind that the rougher the surface, the earlier it will hook.  Dull balls are generally not going to cover a ton of boards.  I hope that helped some and didn't confuse you more.
