I use an eagle industries "rigger" belt. I've had one for a couple of years. It was issued to my team for testing. Many of us in my unit had already replaced our BDU belt with a parachute strap belt. These were the first rigger's belt. The SOE, Blackhawk and Eagle belts are all very simular and will hold in excess of 7000 lbs. I have had to use mine in emergency situations and training ops and will never give it up. I do not have any data for you but I do have operational experience to back up my claims. I hope this helps.
