At one stage when I originally bought in in DEC the heads were round 7.6 to 8c when the oppies were running approx. 3.6c.

Looks like oppies get sold down lower initially, i.e. the bear runs or fear based selling hits the oppies hardest and before the heads. The reverse applies in a bull run I believe. Hard to see this thing moving upwards in the short term in this environment but you never can tell.
