LMI Bluefin + Fathoms 90 + Canon HFS21...anyone have this combo?

While I had pretty much sworn off LMI, I've been without a video setup for my last two trips--have been waiting for something that would deliver acceptable video while still being small and light. I've been waiting (and waiting) for Gates to get Fathoms glass for their Vixia housings, but it hasn't happened and isn't clear it will. Apparently, LMI's Bluefin for this camera gives real one-touch white balance, and works pretty well.

Before I plunge off this cliff, it'd be great to hear from anyone here who has (or has even used) this setup. LMI gives the housing mass at 7 pounds, and the cameras weigh nothing. It looks like they sell a float/life-jacket for this, which suggests it may be fairly negative in the water.

Anyway, any feedback much appreciated.

Actually without lights the Bluefin S21 + Fathom 90 is very slightly positive. With two sola lights and ultralight arms it is very slightly negative. When using a gorillapod we have to add a bit of weight.

The life jackets aren't so necessary with the current systems, but can make a world of difference with older lights systems with heavy battery pods.

I'm sure that others without commercial affiliations can comment on the more subjective aspects.

Strictly speaking, the Canon needs a Fathom 85 lens. The Fathom 90 is for Sony camcorders only, unless I am mistaken.
