both 960 & 720 are 170º (both are 1280 wide, so the only difference is height/aspect ratio and the option of 60fps). as you say, that's good and bad. there have been times when the best/only shot of the plate was all the way at the edge of the frame... so it can't be too bad.
what i'm noticing is that the HERO-960s often catch blurred plates @30fps, taking up enough pixels that they should be readable, while the contour 1080 (1280x720, 60fps) often catches a few frames of clearly readable plate number... despite the contour being on my head (moving around, higher up) and the HERO being on the bike (steadier shots, closer to the ground & plates). i'm confident that 60fps is the difference between getting plates and not getting plates. resolution and FoV are also important, but i'm finding them secondary to frame rate.
if i just rode during the day, i'd get a bunch of contour-1080s (135º FoV) for $140-150... but at night the HEROs do quite a bit better.
