I don't think I could every use any kind of floor frame. I wiggle too much to get comfortable whether I'm quilting or not! I use a 12-14" hoop in my lap mostly. Sometimes I use no hoop. I like the hoop as it's easier for me to find where I left off. But if I'm doing a really large (king) quilt with lots of pins, I sometimes just use no hoop. I've more or less migrated to thread basting the queen/king quilts that I do as it reduces the amount of weight I'm moving when adjusting my quilting angle. I can only quilt in one direction. I've heard that any type of floor frame quilting is most efficient if you are able to quilt both towards and away from you. I have yet to attempt, let alone master, that technique.
All of that said, if you are comfortable, go with it. There is no right or wrong way.
