I am looking into buying a Mirage G4 from a 5 9" 190 lb guy. Im 6 ft and 170. When I put the rig on the leg straps are fine but there is a lot of lift on the bag when pulled up. What straps mainly cause this? Also, which strap is the MLW and which is the lateral? Sorry Im a newbie and am trying to understand all of this. Thanks,

Im looking into buying a Mirage G4 container used. One that I found is from a guy who was 5 9" and 190. I am 165 and 6 ft. Quite a big difference. Is it possible to resize the harness to fit me well or should i just look for something else?
