I got my Tsunami after a fellow BFer pointed them out to me. I was looking for an inexpensive custom frame where I could get some radical geometry stuff done. Cheap (first one I bought was when the site listed price as $650) and effective.

That black frame was me thinking out loud on paper and in email to the builder.

I'm totally committed to BB30 (I have two BB30 SRM cranksets) but it's not the best option for Tsunami - I think a standard threaded BB works best because there are facing/cutting tools available for English threaded BBs. There are none for BB30.

The black frame is a fun frame but the orange one is probably a better one (lighter by 200g). If you read the links above I designed the black one to run with no bottles, i.e. just a CamelBak. That didn't happen (it did for the first few races though, including the shot of me on the bike) so now it wears bottles. In that case the aero tubes don't mean diddly.

I hope to ride the two bikes equally next year, switching on whim to experiment with slightly different setups.
