Fall in the Midwest
Welcome to fall in the Midwest and a property with a lot of mature trees!
John Farrell (friendless) has a wonderful BGG tool with all kinds of listing options. But you have to go to him first and ask to be added to his site. A few years ago I asked that he add a way to sort by weight, and he did.
Search for User "friendless." On his profile page is the link to request being added to his website. When you get linked, the listing by game weight is under "Other Perspectives."
I highly recommend his great website. It does a ton of things.
I second this! Its a great site for slicing and dicing the stats of not only your collection, but your plays as well.
