Because the motor cannot spin as fast as the tubing wants to shoot, we can't just reverse it real fast and try to flip the ratchet switch.

Honestly though, that just shifts the problem of releasing under load to whatever is taking the load while you reverse your motor. So many the real questions should be "what will hold and release the tubing effectively". And for that I think some kind of simple pneumatic hook would do the job best.
I'm not certain you would need to relieve the loading (you may need to)after reducing it by cycling the motor.

If you do, perhaps pushing a high friction material into the winch spool, acting like a disc brake would provide sufficient relief without necessarily holding the entire load with another device.
