You can get a lot of debate/opinion about whether or not to wrap, and if so, for how long. One thing that's pretty clear is that 2 hours in foil is too long and turns ribs a little (or a lot) mushy.
One thing everybody agrees on is that the bend test and the toothpick test are the end point - although some ribs inherently bend more than others so some of us have found the toothpick (toothpick or other sharp object probes through the meat like "buttah") test seemingly more reliable.
So, how you get there is less important than where you end up.
