I think the pistons have -12cc or something like that.

The rope seems to be a good idea, since air pressure would force the piston down.
the air psi needed to hold the vale up will definitely not push the piston down. the main benefit to using air is it holds the valve all the way up nice & tight & makes adding the locks & new spring while using the spring compressor tool much easier.

im sure the rope works ok but the air is quick & easy & wont even budge the piston.
