If you add holes to your paddle you'll avoid hot side aeration, and as a bonus you won't need to use a secondary. It'll keep your curve ball from hanging, and your wife will see you with new lustful eyes. A raise at work becomes much more likely, and the Jones next door will begin admiring your lawn.
Further, the paddle moves a bit more easily through thick, deep mashes. And that's about it. Like they say in the big republic of Texas, Drill baby drill!
