That boom should work fine.
The CL-360 plus modifier and bracket will be less weight than a moonlight with modifier.
The power pack can be put at the other end of the boom along with the sand bag. It doesn't weigh much but might as well get it over there. Handy for turning the light on and off via the battery switch.

Nice thing about using the battery switch is that the light comes back on set to the same power setting. What it will not do however is come back on in H mode.

Scott, Jesus and probably others are using 40" grip arms for short booms. That's another option.

Sounds good, will test how well it works soon.

Another thing I'm wondering about is using this lumedyne speedring adapter from profoto to attach a larger softbox, say a 30x120(1x4') directly to the flash head. I am wondering if it will hold or if it is just too much?

I and some others have been working on ways to directly mount modifiers.
The big problem is weight. The modifier is held on the head with pressure from the thumb screw.
It ends up pressing the modifier annulus against the flash tube. Thus, if the modifier is too heavy the weight starts to pull the flash tube out of its setting. That is not a good thing.

Have you found out how much weight is too much? I imagine a 1x4 softbox with speedring is no more than 1kg

Couldn't think of another word at the moment. :-)

THIS (external link) is too heavy. Its what started to pull the flash tube out of a 360 when I was testing.

Wouldn't it be easier to use the speedrings that mount to the light stand so the strobe is not really involved. I got a couple off ebay and they seem to work, BUT, I don't have any large or heavy softboxs. My largest is 32x48 but I mostly use 2ft by 3ft.

This was my first idea, but then I thought I'd like to have better quality Speedring adapter, the best one I could find is by profoto, they have 2 versions in fact, but neither is perfect and they are extremely expensive (200 each, smaller version is 115) plus they weigh a lot and can be a bit bulky. So it sort of goes against the whole of idea of cheetah lights as a very light weight portable solution.
But I'm just not quite comfortable with cheap china adapters yet, so trying to think of alternatives.

For Cheetah Lights, the best option is the Cheetah Pro Bracket.
It will accept a Bowens mount which is an easily acquired adapter for just about any speed ring.
The Cheetah Light mounts horizontally and the head with bare bulb can be extended into the modifier to optimum length. It The combination is bigger and bulkier but it does make traditional modifiers useable with the Cheetah Light.

There are other similar brackets but they lack the support pad under the light which takes the strain off the hot foot of the light.

That's the conclusion I have arrived at as well. However cheetah bracket isn't available in Europe as far as I know :/

I use the cowboy studio T brackets from Amazon. They don't have the support pad but still work fine. The Bowens mount I bought also fits into my Lastolite Ezbox just fine as well.

Thanks, will consider the cowboy studio bracket.

I know this is unrelated but I couldn't stop myself from wondering if I should get this... Jinbei sun 170 td umbrella. It should work just like para 177 from broncolor. The price is only 670 euro, plus there is a 30 days return policy, no questions asked.
Do you think I should buy it and see how it works? Or is the whole parabolic umbrella thing a marketing gimmick? Plus if I were to use my existing cheetah cl 360 units, would they be strong enough for it?

this is what I've found and used. about 1/2 way down the page there are one for each type of system you have and not anywhere near the price you paid.

I'll also agree with the T-bracket from cowsboys studio. I have a couple and they are great. Plus it's not listed but they have the umbrella mount on them also. You could get three of them for the price of one from Cheetah, while it doesn't have the support pad, it's not that tough to place something under there to support it and wrap it with a simple rubber band so it stays in place

Just to clarify, I haven't paid anything yet. I'm weighing my options first :)
Great advice again, thanks. Slowly narrowing down my options.

Any T bracket will work. If you place the digital side on the rail it will lay flat on the rail and you just need the rubber band for extra support. E bracket will work as long as there is a screw and not a thumb screw that holds the head of the lollypop and your not using adapters.
