Bogen Stacker Light Stand

I'm considering getting light stand(s) for this holiday season. I found out that B&H, now, sell Bogen Stacker series light stands. I searched B&H, Bogen, and Manfrotto's home pages for information on this new product but came out empty-handed. I just want to compare the specs with Bogen 3097, 7 1/2' lightweight pro. Would anyone please point me to the web site where lists the specs on these light stands? Specifically, I need to know the size, weight, maximum extension, and load capacity for these stands; I have the specs on Bogen 3097.

Thank you very much for any help you can provide.
