Oh cool! If you remember where you saw it, can you post the link here so I can see it? Are you going to get the extra shoulder strap as well?
Here is the picture-it's Suzi's DG LMmidi! Her straps were shortened to make her drop 7.5", but on ours with the 2" shortening it would make the strap drop 8" (a half an inch is not that much difference).
I didnt order the shoulder strap because I dont mind carrying my midi's on my shoulder with both straps, but now I am re-thinking if I should add a second zipper or just stick with one (LOVE the 2 zips on the midi!)
