I have the grace pinnacle and if there would be one thing I would change, it would be the ability to lift the top rail so that you can smooth the batting, should you decide to let the batting float as you quilt. The INNOVA quilting system has that feature and wouldn't it be so much nicer to be able to just float the batting rather than trying to load it on to a bottom rail?
I could load the bottom rail by myself until I hurt my back awhile back ... now, I have to have help, and I am learning some pointers that the Grace company doesn't share.
Also, spend the extra money for the leader fabric/sleeves. It will save you many headaches and a lot of work. <wave>
