Q: 7. anyone tried attaching to the bottom handle instead of the wheels? I imagine this way you could roll or carry at any time

A: Hello Mark F,I bought two of these as I thought is was a perfect idea.In my work I use many different Pelican Cases every day and the idea of a back-packable 1510 seemed brilliant. Alas....I've tried to use these straps as the instruction say, I've tried all sorts of mods, longer screws with a D-ring, drilling holes for the straps, etc, but there really is not an effective and easy way to attach the bottom straps other than over the wheels. If you do finally get them attached that way the straps will slip off the side of the wheels and get bunched up in the area and become very difficult to undo. IMHOI wish Pelican would take this idea and do it right. All the best!Julian
