You're basically my height and weight exactly and TE2 fits me like a living glove! No shimming or anything.
ATA is based on the TE lineage so it should do very well.
But, my advice is KEEP reading and researching to make sure you know what you want.
You may have already done that, but it's better to be anxious because you're dying to get it than sorry you rushed.
Ask yourself — if you haven't already — how important are these things to you?

Read the links in my signature for more info too... but, yes, assuming ATA is similar to TE2 — which I've heard it is — it should fit you great.
