Arca Swiss ARCA-SWISS Monoball P1 S (Single) with Quick Set Device - Flip-Lock (Requires Plate) Review:
Compact and light weight yet very stable
It is not low cost but you feel it is made to last. The design is innovative and the reversed design is very convenient when using the tripod on an uneven surface. You get the camera easily level even if the tripod is not. It is very small and compact but has sufficient strength to carry a 100-400mm zoom. A perfect match to a carbon fiber tripod in particular if you have to carry the gear a distance. The quick release plates are not compatible with the standard Arca Swiss ones. This is a drawback and an additional expense if you already own a set.
