commerce shipping

I am trying to enhance the checkout experience and avoid unnecessary customer confusion and mistakes by customizing the shipping section a bit.

First, I would like to remove the default shipping rate -

I am setting a Maximum Shipping Rate for use with the Commerce module.

Currently, I assign each item a weight using the Physical field and this tutorial: http://vimeo.com/33838479

I want to set a maximum of 10, so if the total weight exceeds 10, 10 is used instead.

Attached is the Rule Component used to gather the total weight of all the ordered items.

Should another Rule Component be created, and then run as an action in the Shipping Calculation, to test whether the total weight exceeds 10, and then setting it to 10?

Thank you for any ideas.
