I'm right there with you. My current Yamaha is just under 9lbs. Combine the switch to the Tama Stage Master double tom stand and I'll shave about 11 pounds off my hardware bag.I'm going to get the HH stand. The weight on my current one in 9.3 lbs, the Yamaha is 4.8! Saving 4.5 lbs may not seem like much, but every little bit helps!
I've also switched from my Yamaha direct drive double pedal to my Camco pedal. That shaves about another 5lbs. All-in-all, I'll have shaved 16+ lbs of weight from my hardware bag once all the new hardware comes in.
I figure I can get a total of about 22 lbs dropped if I went w/ the Crosstown snare stand and 2 Crosstown cymbal stands. For a few hundred bucks, for me it's a no-brainer. I just gotta finish some house projects first.
