They occupy lofty perches on the competition ladder, boast two of the three best defences in the league and are traditionally known for their tight tussles.
When the Breakers (7-4) meet the Wildcats (8-4), fine margins matter. So with the rivals' clash in Perth tonight likely to be decided by the little things, and with the Breakers' under-strength big men set for a serious examination, Charles Jackson's hands may be as important as Corey Webster's.
While Webster is enjoying the hottest streak of his career and will again provide the best of the Breakers' offensive threat, Jackson will be tasked with preventing Perth from playing to their strengths.
The second-placed Wildcats possess one of the most physical front lines in the Australian NBL and, after consulting the Kiwi club's injury report, will undoubtedly be searching in the same area for a weakness among their wounded opponents.
With Tai Wesley missing the trip out west after picking up a liver infection from his appendix operation, the Breakers are already short of one of their best performers in the post. Adding in the steady but slow progress of Alex Pledger and Mika Vukona in their return from injury, the onus will be on Jackson to match Perth under the basket.
