What size should I be looking at? I'm average build 6 ft 150 lbs.

There's small, medium, large, and xlarge.

let me know how you like it. i'm looking to buy a good full face for training. i was leaning towards the title platinum version of the same style.

Actually, I'm leaning towards the Title Platinum model myself now.
