Well I calculate the spread for the ACT-Chiefs should be -16.5 (actually greater, I place much importance in H2H which would have increased this by a couple of points).

I calculate the Crusaders-Stormers spread to be -9.5.

SO, I'm taking the brumbies at -16.5 at 2.01,
and the stormers +12.5 at 1.95.
