The parachute can inflate with tremendous force. Parachute deployments can be very violent. If you try to use your parachute to climb out of a tree, be sure to add knots in the bridle at regular intervals so you do not slide down the bridle and burn your hands. Each time you change your harness or parachute, you need to re-learn how to extract your parachute from the container. Your new system might require a different kind of pull than your previous system did.
Indecision is dangerous.
Bridles that are sandwiched between the harness mains do not always release properly during a deployment. Stalling the glider pass vertical while attempting a loop in thermal conditions. It is more difficult to climb into your control bar if you do not unzip your harness first. Aluminum Carabiners can break when not properly cared for. Bad situations can get worse fast.
