This is very good. Its still possible to end up in the back half of the plane (if there are a lot of preborders (going to MCO from my area where it snows towards the beginning of winter this happens, we have had 10 wheelchairs lined up for a flight before) or if your flight is a continuation from another city (so there is a potential to be a bunch on the plane before you get on.
You will be 27 and 28th at worse in general boarding though so finding an empty row slightly past the wings is pretty much your worse case scenario (even if business A1-A15 are full, which happens more often now since they sell those positions for $40 just before boarding)
