Anyone running a TA Zephyr Light (compact double) crankset on their Rambouillet?

If so, could you share what bottom bracket you're using? I'm finding conflicting information about the proper spindle taper and width.

Yes, I am.  And I'm using the TA Axix Light BB with it at 122mm length and BSC threading.  It has a square taper that is, of course, designed to work directly with TA's crankset.  This BB has two separate cartridge bearings pressed into threaded cups that mount into each side of the BB shell.  To tighten and adjust the TA lock rings you'll need a proprietary wrench (or you'll strip the notches in the rings if you try to use a standard BB spanner) along with the run-of-the-mill splined wrench that is used to install most Shimano BB's.

Can't say that I'm 100% crazy about this BB.  It does have the nice feature that allows it to be moved to the left or right a few mm's, but so does something like a Phil Wood.  And it has a seal on both of the cups where the spindle goes through them that seems to deteriorate and bind up the spindle after so many miles/years.  But I got it because I thought it would present fewer problems when trying to use the TA crankset.

I have a Phil Wood 119 sq taper, including rings which I would be happy to sell.

I had a 60cm Ram and used a 119 Philwood jis bb. After I sold the Ram frameset( giant mistake), I bought a Roadeo and use the same combination. The TA Zephyr two ring crank with the 119 bb works flawlessly with my Campy 10 setup.

Yes, JIS SKF. I can't recall whether it was the 116 or 121mm, they advise to go the smaller if on the line. I could pop the arms and measure if really interested.

Symmetrical on the 119mm Phil, I assume?  The TA is symmetrical.  Since this setup works it will probably be the next one I install in my Zephyr configuration.

Here's a link to Peter White's website about the Zephyr Light website.

Yes, it's setup symmetrical. If you use a 116, you will have to offset to the right.
