Ball return all the way, but for practice purposes mostly....
Leave the skirts off the gold crown...so when I pocket a ball but miss position, I can reach down and grab the ball from the return, and toss it out on the table, placing it back in the same position as before and repeat without having to leave my foot off the shot line, so to mark the location for repetition.
The same with scratches, reach down and grab the cue ball and set it back up.
For repetition drills, you can easily get in dozens of more shots in the hour by not waiting for the ball to return to the box, or having to walk over and grab it from the pocket.
