I agree with everyone else to a point - no real difference in carry power from 15lbs to 14lbs for the most part. HOWEVER, if you are big time stroker with a real low rev rate, you might see a few more weak 10's, etc., but with any kind of revs you shouldn't notice anything. My dad drilled a 14 pounder earlier this year to try it (he's a true stroker in every sense), and he has lost a bit of his light carry power with it. When I tried tossing his 14 pounder, I saw no difference between it and my usual 15lb balls.
