We are on the brink of switching from RS A to MM. I tried the free print outs and DD enjoyed them. RS is definitely a great program but I don't think it's a good fit for my DD. I do think she'd do better with a mastery program plus the table top work/reading the directions to herself (I was obviously there to help when needed) really helped her focus. She was always so squirmy during many of the RS lessons. So, at least for us, I think her focusing on the instructions herself, visually, really helps a lot.
Good luck figuring it out!
