8" Light Bridge - Collimation Issues

Is anyone having trouble with their Light Bridge holding collimation? I collimate my 8" every time I take it out and sometimes it's off mid-way through the evening! This is frustrating -- any suggestions (I've checked the obvious loose screws, etc)?

Are you tightening the lock screws down? I think my 8" Zhummel, which is also made by GSO in Korea, is the same mirror as yours, although the mount may be different. Mine holds collimation rather well after I firmly hand tightened the lock screws.
