I am looking for a carrying system that will be able to hold the same amount of stuff without putting as much strain on my back. Cost is a factor, and switching to a bike thats easier on the body isn't. I used to commute on a mountain bike i turned into a hybrid but the fixie is just too much fun

. My current bag is a Timbuk2 Hemlock.

Not to be a totally naysayer, but are you sure its 60-70lbs? That is a lot of weight and seems like more weight then would fit into that bag. Thats like 43% of my body weight.
