I have the Feisol 3442. Compared to my non-carbon 14XX series Gitzo, it's not nearly as finely crafted. But I don't think it needs to be. And I'm an engineer who loves precision as much as the next engineer.

I typically use the 3442 with a Kirk BH-3 and Kirk plates. I have the Feisol medium ball head as well as a back-up.

This combo has been more than adequate for a Hasselblad with a 250mm and 2x tele-extender, as well as for a Toyo AII and a 5x7 Deardorff with an average size lens (one I'm willing to hike with, and not a moster). The tripod IS light, but comes with a center-hook as standard and my camera bag, etc usually weigh enough to hold the thing down in moderate winds.

If winds are going to be low, I'd use it with my 8x10 and a pan-tilt head, but haven't tried it in the field yet. I'd preferably go with the Gitzo for serious 8x10, especially if I was shooting with the camera at a severe tilt.
