Boone Lennon is the inventor of the sliders, these are the product many place on poles, or just hand carried for years. I am sure nastar doesn't,t give a fuc$ but in all other sanctioned series (usasa,ussa, FIS) you are not allowed to use any "devise" in your hands.
15 years ago lots of product to hold and slide on were out there.
I have used a bunch, I would be scared of your pole tips, the idea of self arresting seems, unjust.
Good luck.
