I'm trying to decide between two brands of camera rotating systems for event photography: Custom Brackets v. Newton bracket. Both seem like a big step up from the Stroboframes.

Custom Brackets- Appear to be the best built systems but are a full lb heavier than the alternative, Newton brackets.

Does anyone have any experience or knowlege of either of these two systems? I'm leaning towards the Newton because of the weight combined with the 1D, and potentially the 70-200 f/2.8 but still definately up in the air.
