I have been ripping for years (and years and years).
When I started to quilt after making clothes for many years I figured I did not need to do it (sigh). After a couple of quilts with wavy borders I went back to ripping. I will pull threads for smaller pieces, but I am too lazy to do that for border strips.
That said, some fabrics do not rip well -- then I do pull a thread. I have yet to find border print or striped fabric that is completely on grain so I opt to go with the pattern in those cases.
