Awesome pics, Todd... sure is fun being a proud Dad, huh?

As far as the straight arm... I think the best I ever heard it put was by Michael Braden when he talked about having a bent arm and leaning against a fence post or door jamb. See how long you can hold the weight of your body up like that; then, straighten your arm out to a relaxed state just like it were hanging naturally at your side and see how well you can support your body weight. There's no comparison.
