I saw them at worlds in their booth. They're really lightweight, might have some good uses, but no, we have not attempted anything with these. We're working on 2 lifts right now and I think that's enough

p.s. the 80/20 we have is the smallest available, i think 20mm, and we use delrin sliders for 80/20 which may or may not work well
