My Lenni leaders are attached with Velcro!!! The fuzzy side of the Velcro is attached to the poles with some kind of glue. The loopy part of the Velcro is on the leader. How easy it will be when I need to replace them!!! A little pricey for the first time, but, especially with a Demo Machine (which mine is), it's nice to have an easy way to put nice clean leaders on my machine!!
