I don't have balls drilled up with sport patterns in mind, but I have found a couple of my Rico drilled balls did well on some sport/PBA patterns. It seems to give a more mellow or controlled reaction which is what I prefer on sport patterns even to balls that I would probably not have considered.
Other than those, I usually look to bring balls which I know are more controllable for me, so those are usually particles or solids, and depending on the specific pattern length, either pin above or pin below the fingers to help control the breakpoint.
