Ok time to update:
Installed the hollow version about 2 weeks ago. Pain in the ass at first, but finally got everything dialed in with my chain length and slamming the wheel.
It has been super smooth, has NOT stretched from what I can tell. I use a lot of pedal pressure when I ride and other chains have snapped on me but this one is holding strong! I ride flatland if you should ask.
The ease of breaking it with an Allen key on a slammed wheel makes this thing worth the price alone!
