Anyone used Sirui Tripods?

[Dr. John R. Brinkley]

I saw this tripod: http://www.adorama.com/SIBSRT2005.html: holds 26 pounds

 

And this one:http://www.adorama.com/SIBSRN2004.html: holds 33 pounds

 

...and was curious if anyone had experience with them and thought they were any good?

 

They both seem to hold a good amount of weight and fold down fairly small and seem like the best of both worlds.

 

I'm trying to find a tripod that could hold a fluid head, possibly the Accratech leveler Andrew likes, and even a slider on top, and yet somehow be portable enough to put in a backpack.

 

 

Update: I ended up getting the Sirui N 2004. It can fold down to 18" for storage. One of the legs can actually become a monopod.. It weighs about 3.5lbs...and yet can hold 33 pounds. 6 year warranty.  It was $184 on Adorama. Not cheap for just legs, but to me it sounds like everything you would want for a travelling tripod.

Only got a Sirui Monopod but it´s rock solid. The fastening mechanism is as goo as on my Gitzo boom.
