I have both a cutaway on my helmet, and an RSL. I am a firm believer that EVERY camera helmet should have a cutaway, regardless of what type of camera is fitted. I also know several people that have had to use their cutaways in live situations. I jump an RSL, despite some of the more 'old school' jumpers I work with not supporting the idea, in fact, most of the camera team at my dropzone use either and RSL or skyhook, save one or two.
Having had a hairy moment on Saturday, a pilot chute hesitation on main (with the main clearing and opening at 2000ft as I reached for the reserve handle) and the main opening with enough twists to make it interesting, I was glad to have and RSL... I had a fairly clean reserve deployment and landed in the lading area wthout further incident. I know plenty of people that use RSL/Skyhook and fly camera, and personally I feel that the pros outweigh the cons :)
