Just wanted to drop back in and say thanks for the mounts! I got a Cervelo S-series short Gopro mount + Gopro to Hotshot adapter. The only slight issue was that the captive nut arrangement on the gopro side of the S-series mount was not tight enough to keep the nut from spinning. I ended up having to put the nut and bolt in backwards and hold the nut with a pair of pliers. I'm not planning to swap out the light, so no issues on needing a pair of pliers.
