I'm getting confused over the details of these three boom stands:
Manfrotto 3400 (aka 420CSUNS)
I am interested in being able to safely and securely support an AlienBee with a large softbox, umbrella, or potentially a beauty dish. Shooting forward, horizontally offset from the stand, or shooting straight down from a high position, and anywhere in between. I would likely transport this to location from time to time as well as use it in my rather confined basement.
The 085BS is certainly more expensive, but it seems to have the most stuff included with it. Would it be overkill for my purposes, or just a very solid piece of kit that would last forever?
The 420CSUNS seems to have its load capacity at maximum extension overstated on B&H's web site compared to Bogen's. 13.2 lbs. vs. 3.3.
What considerations am I overlooking?
And what is the purpose of the drop-down pin I've seen mentioned in other boom arm threads?
