I've never used the vinyl masks, and only done a little experimentation with adding hull plating effects, but I do have a few suggestions.
With all due respect to ap me, I do like the sense of scale a well-done aztec pattern adds to a model. The catch is that the masks still have a regular pattern to them and fellow modelers are familiar enough with it that it's lost its effectiveness at appearing "random." Unless you're building a TNG-era ship, aztec alone won't match the on-screen appearance.
To match the look of the movie-era ( ST:I-VI ) hulls, what's needed is an added bit of work. Preshading randomly-placed radiating bands on the saucer ( and other patterns as needed to match the different patterns on other areas ) that mesh with the notches of the aztec, and follow-up layers after with andomly-placed rectangles, will break up the aztec's regular pattern to better match the on-screen appearance than aztec alone.
Have fun with the project, whatever techniques you decide on, and I look forward to seeing the results!
