Except for my studio tripod which is a heavy weight Manfrotto, I have been using Sirui for years with never a problem. If you need to spend really big bucks, then you have to go with Really Right Stuff. The Sirui carbon fiber products are great and less than half the cost of the major brands.
With respect are you actively using your gear commercially?
I travel all around with my stuff and prefer to go with product that i normally can trust to a high level of confidence. It is an investment in a tool not an accessory.
