Shipping rates under 50lbs, free shipping over 50lbs - how?

Hi,

How can I make shipping work as follows (I'd like to use FEDEX if possible?):

Anything UNDER 50lbs calculates shipping and charges customer appropriately.

Anything OVER 50lbs is FREE Shipping.

Any help is appreciated.

Thanks!

The easiest way would be to use Restrict Shipping Methods, which would allow you to restrict Fedex from appearing over 50 lbs and Free Shipping from appearing under 50 lbs.
