The RRS tripod appears to be a hybrid with regard to specifications. It is closer to a 5 Series Gitzo in load ratings, but weightwise it resembles a 3 series. The RRS info doesn't mention the size of the tubes. However, RRS talks about a "big and thin" philosophy. That makes me wonder if the tubes are as large as the 5 series. The RRS tripod has a number of features that addresses some of the criticisms leveled at Gitzo as well as some new features.
I'm wondering about the vibration comparison. If the RRS tripod is structured like a 5 series Gitzo, then a comparison against a 3 series Gitzo may reflect greater vibration damping because of the size of the tubes. IMO, a 5 series-sized tripod weighing in at a 3 series weight is a good thing. Also, the price would be comparable to a 5 series.
I assume RRS did not include g-locs because of patent issues. Personally, I think g-locs add to the strength of a tripod/monopod design. It is ashame RRS could not add it to its design. I wait to see how the RRS legs turn out.
