I done 15 lap quilts for Christmas on my Pfaff 5770 and Babylock Ellegante, Support is a big factor and centering each block as you hoop it. They turned out very well, but it does take a lot of time. You must be sure the batting is not too thick or the hoops will pop off in the middle of the pattern and then you have to pick it out and start over as it is very difficult to match it up again.
