I was looking at this photo again:
And I remembered a thought I had while riding this past weekend.
I think I and going to pull the cinching straps out and re-install them with the cam buckles on the rear of the bags. My reasoning is that with most crashes the bike will be moving forward and with the cam buckles on the back of the bag they are less likely to impact something hard and maybe break or crack.
Not a criticism of the bag... just an adjustment I am going to make.
