My current system uses a combination of polyethylene and vinyl and total run is about 12 feet. If it was silicone this means CO2 loss from the tubing would be 79%!!? Is there something wrong with my math?

If not, it seems you really do want to avoid silicone. Amazingly, Foster & Smith has a semi-automatic CO2 injection system http://www.drsfostersmith.com/Produc...&N=2004+113924 that comes with 20 feet of silicone tubing.
