Bruce. I'm not a fan of EZ line. I know several people have great results with it but it's too fickle to temp changes for me. My main go to is streched sprue but that also has it faults, several of them.
I purchased some stuff called Uschi. It's a little pricy and I haven't used it yet, but it is extreamly elastic and watching some YouTube vids on it, it looks very easy to apply. My only complaint with it so far, which shouldn't be a complaint, is that it is very small. That makes it more to scale but harder to see.
