I have a Z44 that I purchased over ten years ago. It has the wooden poles and I have to attach my leaders by thumb tacks. I understand the new frames are metal and have a different method for attaching the leaders. I also have leaders for the sides, but I believe the newer Z44s have bungie cords for the sides. I would strongly recommend those. I used my frame for basting because I never mastered quilting away from myself. However, I've given strong thought to getting my frame back out of storage and giving it another try. Congratulations on your new frame. I know now excited you must be. Keep us up to date on your progress.
