I just weighed a Z-240, diffuser, YS adapter, 8" arm, 4 AA batteries, and a charger at a total of 1050g (corrected from 1150g originally stated). Considering we have an 800g strobe here and need to add a battery-arm, arm adapter, clamp, and charger I'd be surprised if they are comparable in weight. Matters get worse when you add a second battery. I share my AA charger with my modeling light though not everyone does. AA chargers are small and light.
I would imagine these are preferable for wide angle and small enough for macro assuming you can accommodate the arm length. I think, though, that the travel weight will be heavier. Perhaps, Jeff, you could weigh and arm, clamp and charger so we can see the tradeoff. How long is the arm?
