Was interested in the Velbon Ultra Luxi or Ultra Maxi for a travel tripod, but haven't gotten any personal experience type feedback on it soo...What about these??? Do any of you have any personal experience using any of these? I really didn't want to spend $200-300 for another tripod, but I want a lightweight one tripod that I can throw in a backpack. These are about 1 lb heavier that the Luxi or Maxi, so I'm not sure if I want to carry a 'portable travel tripod' quite that heavy. The only reason I'd get any of these is if I get really bad feedback on the Luxi/Maxi (since I already have a CF tripod) or I get really awesome feedback on these. I actually lifted one of these El Carmagne in the bag at the store, and I personally thought it was a lttle too heavy for a travel tripod for me. I'm a small person, so all this, plus the gear??? I don't want to end up leaving it because in the end it ends up being too heavy for me... Anway, I'd apreciate any feedback on these...
