I looked up this bag, and it appears to be just as tall as mine, though a bit narrower. I'll try to post some pics of mine up this weekend, could you post some of yours? I need the width to carry my work laptop when I ride into the office, could you fit a 15 inch laptop in your bag?
Here is the old Cortech, you can see it has a steep pitch and the front of the bag is quite tall. One of the neat features are the sewn in bungee cords. Really simple to hook on and off the bike, like in seconds. I believe that was removed in the 2.0 version. It could easily fit a laptop if you expand the side pouches.
Here is a photo of the tailbag when I was down in Florida.
It's expanded all the way and it alone held everything I needed on that trip for an entire week besides the clothes on my back and the boots on my feet. Oh yeah, and my helmet!
This is the Nelson Rigg bag I have on order.
Here's the old version on my Ninja. I really like this design, it has a very rigid construction and a low profile. Plus it ties down under the seat so it's nice and tidy without straps hanging all over the place. I'm selling this particular bag with my bike simply because this version has the expansion zipper below the tie-down straps making virtually useless. Also with this version the rain cover is sewn into the main compartment taking up a little bit of real estate and the new version is simply a loose cover.
It's not huge like the Cortech but I can carry all the daily stuff I need, gloves, sunglasses, earplugs, water bottle, tire repair kit and a few other odds and ends with room to spare. It won't hold a laptop though.
