I've the short-bodied StrongBag and it has held up well. If you commute mainline it'll fit the bin going in lengthwise. It's also often in the back of an ERJ and has come through unscathed so far. I had an LW bag, but it didn't hold up as well as I hoped (although it wasn't bad overall). The SB is much lighter and is doing better than the LW over a similar period of time.
