A separate forum category for size comparison tools
I'll add this suggestion to Darcy's Your Wish List for these forums thread, but we need to put tools like thax's spreadsheet somewhere easy to find -- either stickied or in a separate group with other tools for size comparisons. These questions come up a lot in the forums. Sometimes they are specifically addressed in threads that compare specific bags like the Empire Builder and the Zephyr as in the first and second posts by Zasky. Sometimes we point to threads like the Pictures of Multiple Bags Together thread. Sometimes we point to movies that show different bags together. And somebody once posted about using http://www.sizeasy.com for a 3-d visualization comparison of products by size. Here are some examples of such comparisons for various Tom Bihn bags (you can search for others at that site or construct your own):
These kinds of tools should be together in one place.
