Will a Genesis 400 hold a 53" Elinchrom Octa?

I'm going with Genesis lights with hopes of upgrading to Elinchroms later, which is why I went with the Calumet lights. With that said, are the Genesis 400's sturdy enough to hold a 53" Elinchrom Octa? I just don't want to put in on the light and end up breaking it.

Also, I was wondering how well the Genesis lights work with a Vagabond II or other portable batteries? Anybody had any luck with them?

I have a 59'' Octo box on a Genesis 200. Now problems with it. I just make sure that one leg is pointed out with the box direction. I just do it as a safety precaution.

When attaching a large or heavy modifier to the front of my Genesis, I often will also attach a bungee stretch cord to the back of my light with one end clipped to the handle ... the other stretched down and slipped over a light stand tightener fitting. That prevents too much strain from occurring on the Angle adapter and preventing it from starting to droop or slowly shimmy down during the shoot. Works adequately, and acts like a courterweight to the modifier.
