Not fond, personally, of monopods with the fold out legs at the bottom. For me it detracts significantly from the almost non-existent footprint of a monopod, which is typically the reason I'm using a monopod in the first place; but that's me and my shooting style. Carbon fiber is great for the weight savings but I find it can "tremble" at times; not a deal-breaker for me, but it can be annoying. If you can live without the fold-out feet and still want the weight savings of CF, maybe consider something like the Oben ACM-2400 and put the money you save towards a really good ball-head...
