There are so many ways to mount a quilt, and I think they all work with different advantages - and disadvantages. I haven't tried the product you mention, but I did make my own leaders with velcro. I found that I didn't like having to sew the quilt back onto those secondary leaders any more than I liked pinning the back to the primary leaders. I decided not to try the zipper systems for the same reason and went back to using pins on the primary leaders - until I bought red snappers. I'm using them now, and they do work well, but I'm not sure that I'm getting the back quite as straight as I did with pins. At least I'm not getting stuck with the pins, so I like that part.
