I'm with Dale here, your best bet is to go to your local pro shop and explain what's happening. Have them watch you bowl a few shots and they'll have a better idea of how to help you. Without seeing you bowl, it's hard to make any sort of worthwhile suggestion.
That being said, I'm going to make an educated guess about what's going on. I have a Full Swing in OOB finish drilled for length and when it wiggles, it usually due to the ball burning up too much energy in the front part of the lane. Moving left and finding more oil usually solves this problem for me. If the lane conditions are true medium / dry, this is likely the case and if you want to use this ball in this center, you may want to consider polishing it so that it will store energy better. What lane surface do you bowl on ??
DISCLAIMER: Keep in mind I'm basing this opinion solely on your description of ball speed, rev rate and lane conditions coupled with my experience with this ball and this is merely an educated guess.
