My 1st quilt frame was the Grace Pro 10ft. Had issues with the poles bowing and the tracks cracking. Added conduit over the original poles and screwed them together and they worked great. The track I changed out to a metal "T" shape tracking I think I found at Home Depot or some place like that. Also worked great. I've since given the frame away and I also had a stretched Juki 98Q on that frame that worked great with it.
