I'm surprised that several brands are releasing new freecoasters that are breaking away from the KHE internals. I had a Colony coaster back in my street days that was entirely KHE. Within the last few months we've seen the Profile Z-Coaster, Eclat Blind, and now the WTP Helix. Out of the half dozen coasters I have used in the last few years, not a single one delivered completely without fail. I look forward to seeing how this new "generation" of hubs turns out.
