The Buffel LM-403C is a custom model made for the ZA market. To understand why, you need to geek out a bit on tripods.
 
There are many factors that determine the rigidity of a tripod leg, but the two main ones are 1) leg diameter and 2) section count. Leg diameter is the simple one - bigger is better and 40mm is the largest tube size that Leofoto makes.
 
Joints perform an essential role in tripod design - they lock telescopic leg sections, which allow tripods to extend very tall, but fold down to a practical size. The more joints you add to a tripod's leg, the shorter it folds down. 
 
Joints also compromise rigidity - if you compare two tripods with the same leg diameter, but a 3-section and a 5-section version (e.g. LM-403 vs LM-405), you'll quickly see that the 5-section has a lot more flex.
