Taking ranked seriously Hi all,

I'm finally going to take ranked seriously this season playing exclusively hecarim jungle and wanted a few tips regarding runes.
For Hecarim I usually take conqueror&gt;triumph&gt;Alactrity/Tenacity/last stand then sudden impact &amp; ravenous hunter but I know others take phase rush instead, or even predator. 
My question is this: Which matchups should I take each of these pages into?

Cheers
