If I use the zip ties it is on a clock that would have a lighter, weaker spring than even the average American clock movements....I have been bitten by many a mainspring and I highly suggest being over cautious. On most mainsprings I use the "C" type steel clamps or whatever they are supposed to be called, not sure....I use the tie wire alot also, mostly for those Korean movements and for the movements that it is difficult to get the other clamps on. The wire is called tie wire and used for tying rebar together, a roll is cheap and lasts a long time, has many uses in the shop. Also as a side note...make sure that whatever you use is as close to the center of the spring and that the spring is completely unwound when captured, (sticky mainsprings fully unwinding unexpectedly are a bit of a scare and can cause damage as you disassemble).
Have a great day, William
