Personally the weight of the head isn't an issue for me - I like the fact they're not just going as small and featherweight as possible but putting some nice design thought into the look. The cabs is where (for me) weight saving makes the most sense, especially as there are so many great sounding lightweight options these days (and as you say @la bam, Laney did it themselves with their last range!).
I'm still very tempted by the 500W head and the 2x12 cab for me new projects, but I may choose a different route altogether if I even change anything in my rig...
