Anyone lead climb with a chest harness.

Had a recent lead fall where foot fell behind rope at lower piece of gear. I wonder if chest harness would help prevent a flip. From anyone that has experience using chest harness, what are the disadvantages. 

The chest harness and normal harness would both flip you if a foot happens to slip behind the rope. Happens to all of us but just have to be wary about where you place your feet. Hope this helps!

It’s much easier to just not get the rope behind your foot. 

The study above [learn to make a clicky] just says that a sit harness doesn't flip you over nor cause back injury. They concluded that most severe injury was caused by smacking the rock.

Getting caught be the rope, upside-down and wearing a chest harness whips you back upright. Yeah WHIPS you upright!  This can cause severe injury if you get whipped into the rock. You're still going to flip upside-down if you catch a foot on your rope.

Highline workers are required to wear a body harness, so the whip around isn't what hurts you. It's the rotational whip into the rock wall.

Anyone out there actually used a chest harness and have some personal anecdotes. 

I don't have 1st hand experience, but was able to find this:

Pros

• Potentially distributes loads
• Potentially protects from certain spinal injuries (e.g. less likely to scorpion)
• More likely to bring a climber passively upright after a fall (e.g. if unconscious)

Cons

• Bulky/expensive
• May add additional spinal compression
• Off-center attachment point may create more of a violent twist/flip if not falling feet first (e.g. rope behind leg)
