Sell me on a Scion Build

Hey all,

I've recently started re-playing PoE this patch, and I'm keen to play a Scion. In the previous patch I played a Lightning Arrow Ranger to mid 50s, this patch I've just played a Tornado Shot to about the same. I'm drawn to the Scion, possibly Ethereal Knives. Would any of you kind people like to suggest something for me? Doesn't have to be EK (and btw I've checked out ZiggyD's EK Shadow/Scion and balurski's RF-EK caster Scion - but if you like them you can recommend)

Thanks in advance for anyone's input
