I am thinking about getting a larger umbrella style octabox for my CL flash, and right now I'm debating between the Softlighter II (60 inch), and the Paul C Buff PLM (64 inch, with the optional front cover).

They seem to be identical when it comes to setup, ease of use and versatility, but I just can't make up my mind.

Which one of them would you choose for your CL-flash, and why? :)

Ginga. I can not comment on the PLM, but I do have the 46" Softlighter 2, and I really like it!

It's little bit too small for full body shots, so the 60" should be a lot better. If that is what you are after.

Both of them are big enough to suggest that you will want to have the CL-XXX mounted on a Pro Bracket or similar.

I have all the PLMs and love them. I have two softliters that haven't been opened since I got the PLMs.

:cool: I'm hoping that the new diffuser panels follow soon. Also the bulb protectors.

Maybe they're on the truck. :-)

Remember that list that Edward posted here a month or so ago. I think they were included. And, I think he said they were going to be in the container.

We'll have to wait till he has it unloaded. :-)

If the 2 to 1 cables are in there, I may sacrifice a Yongnou manual speedlite to see how fast I can get the recycle at full power. :-)

Wonder it there is an electronics engineer who can tell us if a capacitor can handle that kind of in-rush current.

C'mon, David. Take one for the team.

It could be a spectacular failure. :-)

I read somewhere the claim that it doesn't increase voltage so its just more electrons moving into the capacitor. Not sure what that affects, or how it improves recycle time. I thought it was the high voltage that did that. Doubling up at the same voltage just means more mAmps from which to draw.

You only get more electrons to move by either having a higher voltage or a lower resistance.

They can't affect the resistance inside the flash. But they can affect the resistance in the battery pack. I.e. they can make sure that the battery pack can keep the voltage up when loaded by the flash, instead of the voltage dipping down when the hungry capacitor tries to gobble what it can get.

I expect that's how it improves recycle time, twice the source of electrons. :-)

Half the current from each source, so each source can better manage to keep up without the voltage dipping. So end result is a higher charge current and hence a shorter recycle time. And hence also more heat issues in the poor flash :p

Worst comes to worst, you wind up with a viral Youtube video.

Oh, so you want me to video this experiment.

What if my hair catches on fire? I make a really ugly bald guy. Come to thing of it, the hair probably doesn't make much difference. :-)

But the video would go even more viral :p

(1) Yes please. I promise to watch many times and enhance your 'score' - you even could become a high flyer (again).
(2) My parents always taught me that it was the height of bad manners to disagree with someone without incontrovertible evidence to back up such a stance. I wouldn't want to be considered ill-mannered!

OK, OK, ducking and running for cover. :oops: :lol:
