If price, portability, and lightweight are key considerations---as well as TTL, HSS, and being able to control power from the wireless remote are required, I would look at the newly released SMDV BRiHT 360. It doesn't have quite the power of the Godox 600 and all her cousins, but it is substantially lighter and smaller, and from what an associate photographer tells me, the SMDV remote is much better than its competitors. I have no interest in purchasing the SMDV as I am fully invested with Profoto and no longer doing weddings--which I think the portability of this light makes it ideal, but have been asked to test/review the SMDV since the distributor knows I have the Profoto B2 system. I've instead let associate photographers more familiar with Godox et al. use the SMDV lights, and so far comments have been very positive. I'll probably consolidate their comments into an informal review on my blog at a later date.
The lightweight portability means it is much easier to put on a monopod as you have been doing or use a light stand without worry about being top heavy. Supposedly more power than B2 (haven't checked specs with light meter yet), yet light and compact. Reflectors are surprisingly well built with similar metal as Profoto reflectors. Very easy to stick one or two light kits into a small photo backpack.
