You're welcome.
For you (and me) 8'1" ceiling would be fine. You want at least 2 feet of clearence above your head. The hyperformance jump rope is easy to trim, the rope will come unattached to the handles. Attach one end, to one handle, then put one foot over the middle of the rope, and draw it up so the rope is taught and the end of the handle is by your shoulder. Have scissors handy, so then you just pull up the loose end of the rope, and snip where needed. You will probably remove around 5½".
