I would not consider the PSC Infinity to have a vented booster, because you need to tape the booster/upper stage pairs together. I believe the reason for the holes in the booster centering are to lighten the weight of the booster and to help deploy the booster's streamer. The PSC Infinity flies pretty well, but the booster does not tumble, hence the included streamer. It stages pretty low with B6-0s in the booster.
