In my experience EZ line has good and bad points.
On the plus side, the elasticity makes it very forgiving and you will always (except see below) get a nice tight line. You don't get a curve radius whenever there is a slight bend - on exiting a fuselage hole for tail rigging for example - that can happen with mono. You can even tie this stuff off in a knot and trim the spare. It takes CA reasonably well, can be painted with care, and loses some of the flatness (especially the thinner version) when stretched. You can even thread it through 0.5mm brass tubes to replicate turnbuckle bodies or ferrules, however it helps to cut across the tread at an angle to get a point to start the threading. In my experience, the stretched line helps the structure, if not with rigidity then certainly holding everything together - so if one wing moves slightly when you rig the second side, you don't get any slack.
However, as others have said, it can twist and have varying thickness dependent on tension. Threading through brass tube although possible is very difficult and frustrating. Painting has to be done after fitting, as if done before fitting the paint can flake or look patchy after stretching. Also painting after fitting risks splattering the rest of the model surface. I compromise by painting mine before fitting but stretched already. As for CA, it can take it too well - if you use any more than a tiny drop at an eyelet or into a surface, then the first mm or 2 of the line can become offset compared to the whole line, due to the glue altering the tension at and near the attachment point.
If you already have EZ Line and various mono, just my thought but why not try a practice run? Maybe use an "empty" sprue and rig between the sprue structure and compare the types against each other?
