Hmmm I thought I'd replied so apologies if this appears somewhere else too.

As for "oomph" how much air are you guys actually looking to move?

Admittedly my work now is 97.5% weddings, the rest corporate so I'm not doing bam jam 18ths or raves but in 3+ years of using my Nano 600s which I'm sure aren't a patch volume and bass wise on what's out there now, I've never once been asked to turn them up.

I am hiring a nexo rig for next weekend but that's a 300-400 person do in a massive marquee so not a "standard" wedding gig but even if I was doing a dozen of these things a year, it still makes more sense for me to hire in a big rig and keep a portable light stick shot for everything else

Sorry I should have concluded: the stick systems are never going to sound as full as a sub and top set up but for mobile work, I really can't see much except really big jobs needing anything else.
