I know the struggle with finding casting reels when you're a south paw, we just don't have as much to choose from. I'm not sure how many set ups your looking to have but 6'6" won't be long enough for deep cranking. Most deep diving crankbaits are around 1oz and u will need a strong enough and long enough rod to increase casting distance to get to those deep depths. The 6'6" duckett rod u mentioned should be fine for shallow cranking. I would recommend the Fritts perfect crank speed stik by lews in either 7'6" or 7'11". The reel with the 5.4.1 hear ratio would be better suited for deep cranking and the reel with the 6.4.1 gear ratio would go better for shallow cranking.
