DAO > Ill check the latest info on the YN's i got. I think they recently upped the specs a little (hopefully more than just on paper). This might at least help others make a better decision when buying new gear.
Unpopular > Battery powered monoblocks etc are too large for my kind of work. I mostly do run and gun situations. Will you believe it just setting up my cameras under a public bridge where everyone is allowed to walk etc triggers a defensive response from illiterates in camera laws. Just position these small flashes and try taking a picture and ull find some embicile (who isnt security or law enforcement or anything) trying to tell you that you shouldnt be taking pictures, OF A PUBLIC BRIDGE.
I had this situation last week, because i had my subject stand in front of a huge cement block, there were 100s of them lying by the pavement for an upcoming public bridge construction, in a public area, we were not even causing a blockade or anything because it was an open public field away from the road. We had a security nut-job telling us firmly we shouldnt be doing photography there since the blocks belong to his company. But they are all lying a public garden field and its a public bridge which means even the blocks are public property. I didnt trespass to take the pic. Yet he was kicked up (and was drunk too) and i asked him to buzz off in no kind words and he was trying to create a scene.

. Was he thinking the concrete blocks will melt from my flashes popping off ? All this for my small little petty flashes. Imagine taking out a full lighting rig.
I think if a bulldozer is standing on a public road and its lonely and your not causing a problem/blockage then you have every right to stand in front of it and photograph it. If it was sensitive material then why would it be on the roads ? I think a lot of photogs face this problem at some point.
So at the moment i wouldnt want to opt for large lighting mainly due to portability. But maybe in the future, id love working with such powerful lighting but im at a handicap to store and cart them around. Also added to this is the fact that they are too expensive for a non-working professional. I would buy them in a jiffy if i had a revenue recovery model. But buying 8 flashes with 2 camera bodies etc when theres zero financial return isnt viable for me.
