Had my LW bag for 8 years and won't buy another one. Frame bends, sharp edges will damage things, heavy, etc etc. Parts get loose and periodically need to be tightened and adjusted. It has worked well and been a faithful companion, but I commute and whatever bag I buy, I am hauling around half the year.
Once this bag dies (probably has a couple years left in it) I will probably get a strongbags.
