i was going to say the same thing. tesla + solid pucks. great bindings and 2kg weight savings when you fly.
yes... the idea is getting more and more tempting, especially for the flight to AK. would also reduce the space needed.
what pucks are these? DIY or from a manufacturer? If DIY, what material did you use? Mind to share the measures? (brother has all these fancy carpenter/locksmith machines, could give it a try)
