There appears to be several schools of thought on egress and deployment of an emergency canopy. Having a plan and rehearsing it regularly is the key, I believe.
I was taught to hold one hand over the D-ring as you egress (if possible) to keep it from flapping around, then grab the D-ring with both hands and punch straight out away from your chest (push/punch vs pull.)
