Just sold my 53" Octa, I love and use the deep octa for lots of tabletop, still life and for back/edge lighting but generally if I'm going to use an octabox on a face I'll use the 69" Elinchrom, I use that for so much, it's light an easy to set up too.
I was just picking up a new Mola BD and was looking at the Ranger A head, jeeze being used to Elinchrom monolights the Ranger heads are less than half the size, it's the power pack that gets big, I saw a Ranger RX Speed power pack setting near a Quadra power pack and it was like a truck next to a motorcycle, huge difference.
I just wish I could use larger modifiers on the Quadra, it's essentially the same power as my BX400's which work with my 69" Octabox beautifully. If we could just use the Quadra power pack with the Ranger head LOL.
