Feral DPS WOTLK, Which is best Strength or Agility (gems)

Feral DPS WOTLK, Which is best Strength or Agility (gems) . Sorry for the long video, I added section markers below to make it easier to get to things you are interested in. I show a bunch of my rotation and even some macro creation in this video, but the main goal was to see how regemming Strength to Agility (all gems) would affect my DPS numbers on a heroic dummy. I am not super good, but not bad and I am not trying to do this as a 'look how good I am' because I honestly need some advice :) Notice during the regemming how the 'pawn' advisor recommends strength gems. If you have some helpful links to point me in the right direction, please link in your comment, all criticism welcomed. Enjoy!
