To reduce the pull force, push the handle in the direction that the protective ripcord housing points - rather than straight out from your chest. The ripcord housing on the Para-Cushion L-39 comes over your shoulder, so push the handle down toward your feet. By having both hands together on the handle, you also reduce the chance of the canopy or lines entangling with an extended limb. -
