wrongo - I have jumped with Airspeed, FX, and PD Blue& Gold. Only in rare cases do they wear weights. Weights are used to compromise for a higher surface to mass ratio, not to pick up a blistering fall rate. The mantis (or whatever you want to call it) actaully promotes a slower fall rate. BTW, the wind tunnel in Orlando maxes out at around 120 mph. I do agree that a 30 mph difference in speed will make a differance in your arm out the window, but a 5-10 mph difference in fall rate, doubt it. The "conventional" wisdom once was fall as fast as you can. Today's idea is to get a comfortable jump suit and fall in a relaxed position giving a much better range of motion and control. (FWIW, a couple of years ago an FX member convinced our point person to remove his weights) Dave
