If you plan to use it on your new Sophia V2, a 30 foot roll is going to last a while. Let's just say you use 12 inches (more than you have to) for each build. That would give you 30 builds. I can make a coil last 6 months or more 30 feet is going to last me several years.
Is there a trick to getting a coil to last 6 months?
