The single most important thing to me is the quality of meat I get home with. I ask for extra lean ground beef which cuts not only the weight volume, but also the freezer space.
You can take a few steers to the processor and some slightly heavier ones live weight have a lighter hanging weight than others.
I asked that mine hang for 12 days or so.
In the end, you get home with what you get home with. Some times you do a little better than others. I would not get bent out of shape over a few percentage points. It doesn't make any difference in the freezer.
Great eating steak and beef in general, in the end, is what you are after.
When you find a good processsor, stick with them. I have been going all the way to Hamilton, TX the last few years.
