There's a 60fps hack for the ContourROAM, and I've used it, but the audio quality is terrible. It's effectively a really old firmware version and it means the audio (which was fixed in later firmware) suffers greatly. Definitely makes a visual difference, though!
I wish there was a way of hacking it in the newer firmware... On the other hand I don't really need to hear my wind noise and heavy breathing much anyway. I'll try this with my new (old) Roam and see what it's like at 60 FPS. I'm also not a big fan of the wide angle lens common to action cams. I'm debating about changing it out for a 90 deg lens.
