I'm using AcuteB and Compact (600Ws). I'm using Skyport for triggering as they are simple a carry-over from my Eli days. No remote power control - Air on an Acute BII would be sweet (vs the simple triggering in the latest iteration). I really should have moved to PW given the R versions of the B I'm using, but quite simply haven't gotten around to it.
When I shot Eli I'd hoped the Quadra would do the job re: small, light, remote power but while I know many folks love it, I was so disgusted with the lack of build quality/robust design or inherent fragile design of teh Quadra heads and adapter (see my post in your WTB post), I gave up.
My opinion only obviously, but I describe the Quadra as "DLite construction meets Dynalite (head) design meets (near) Ranger price point". While the rubber trim on my Quadra pack wouldn't stay on to save itself and it had almost too many features (lost of menu trees), it was a nice powerful and small feature-rich unit. The heads and adapter were another matter. Your average speedlight is much better built than a Quadra head IMHO.
But, everyone's mileage and intended usage is different. Limit it to what was designed for, be careful what you mount on the heads and you're good to go. Like all Eli lights - great light, nice tunability and controls, but they need, for me, to marry the same level of physical construction and robustness to the effort they put into kicking-out the lumens.
I am 'concerned' Eli, while adding more & more electronic features in their new and updating products, is cutting back on (or not addressing) existing robustness issues to be able to implement the mods at a given price point - EVERY unit, DLite, BXRi and Quadra required some DIY work, time, $$ and limitations of usage to get and keep working right.
Even the latest DLites ITs - thicker plastic and BXRi swivel (which while stronger still needs to be modified) but same punk-a@@ weak dovetail system (two 1/8" x 2" strips of plastic) as the old one mounting the swivel to the bottom of the case. Negating any value from the thicker plastic - other than for Marketing purposes. I guess 101 new electronic features and options make for more attractive Marketing (and are cheaper to implement) than 'built like a tank' design and construction.
I'd considered the Ranger given it's excellent rep, but was reluctant as would not be surprised, to see the Ranger II start to mimic a more BXRi-like construction - more plastic, less metal, etc., but a myriad of new (and marketable) bells & whistles. However, the former is more important to me than the latter.
I'd been lusting after a move to PF for some time and after issues with my DLites and BXRi re: build quality and QC, the Quadra was the last straw and I jumped on some deals PF was offering last Fall. Would have explored Hensel, but in Canada, forget it - you'd think they didn't exist.
A Ranger head on a Quadra pack, while killing any modeling light and larger, would have worked great, but by that time I was a lost cause to Eli.
