Do not attempt to change perches without taking the springs out. The coils could rip a whole in your chest if it lets lose. Get a good spring compressor and it will take 1/2 hour longer per side. Don't play with your life or anyone around you, not worth it.
Don't risk it. Use a spring compressor, unless you don't mind a gaping hole through your chest. Try to use the internal compressor intead of the external hooks. I don't refer to them as suicide compressors for nothing, but something is better than nothing.
