Thanks guys! Here's what I've learned:
A sidways quick stop may get you stopped faster than a forward quick stop but not without increasing the risk/exposure to mast bumping, vortex ring state, and unknown side loads to the tail structure.
Increased airspeed agravates the situation.
Avoid the situations that would nessate the need to use a sideways quick stop.
The benifits do not out weigh the risk.
