I Love my Veto Tec LC, let's get that out of the way. I am doing a lot of service work and the shouldering of my bag takes its toll on my back. Walking around a lot and climbing ladders is making the LC a pain sometimes. Does anyone have some real-world time with the Tec Pac? Can you offer any insight and experience with it? For $250 I want to be damn sure about it. Thanks in advance.
