Not to be "Johnny Raincloud" but I think the Brain Cell might be the most important item they sell here?
There is no padding on the bottom of the TriStar so I suggest sticking some foam or something there when carrying a computer if not using the B.C.!
The Brain Cell is unique among computer protection in that they are designed to sling the computer above the bag bottom so that a drop will let the computer swing or droop down inside the Cell but never hit the bottom.
I don't know of any better protection anywhere else.
