I have the fenix mounts but do not really care for them much. They have some movement in them while riding and the angle adjustments aren't fine enough to be of any real value. They also have the small mounting screws that are a pain to tighten. (not as bad on my fenix, but a real pain on my P7)
The larger version (cycloblock IIRC) is much better for a larger light.
