That's kind of a broad question, so here is a broad answer.  The total volumes are considerably higher for the tour PBA patterns.  Somewhere in the neighborhood of 25% and higher.  Viper in particular is 33.4ml for the PBA tour, and Viper PBA 50 is 21.7ml ... that one in particular was very different.  The shapes are generally the same with some tweaks, particularly in the track areas.
