You guys are convincing me! I'm still kind of nervous about the lack of reviews, but I'll go with the Aluminum S6. Now I just have to find out when B&H will have them back in stock. Otherwise I'll just buy it on ebay for the same price.
I think you'll be more than fine. Tripods are one of those tools that are expensive and non-sexy but a very important tool. A cheap tripod is well really crappy 99% of time. Motion capture is so critical. Check out Adorama as well for the Benro model you are looking for and please let the community know how you like the tripod.
