Wow. Thanks for all of the comments.

I'm leaning toward the 4.

The Teton 5 is interesting, but I am having trouble with the thought of paying about $50 for 0.5 of an ounce. The Teton 5 specs are almost identical to the Tioga 4. It seems that there are just more weight-saving holes in the Teton. Is there something I'm missing on that?

Thanks for all the thoughts!
