I use a Sirui P-326 carbon fiber monopod, which is a travel model, though I've found its minimum length very useful when trying to do some creative composition down low in bad light.
I recently spent almost five weeks traveling in Europe and Asia, and it was my first extensive use of a monopod and head. I used the Sunwayfoto monopod head and rotating clamp, and loved it. I use the Arca-Swiss system for my L-bracket and feet, and this setup worked wonderfully. The head is less than the Kirk and RRS models, and the quality is excellent.
