There is no real "spring formula", and since the claw is quite adjustable, you really should be fine with either two or three springs in nearly any pattern, those .009 are fairly light so compensating for their tension isn't difficult.
It's really a matter of feel to be quite honest. Start out trying the two spring "\/" shape, then go to the three spring shapes "lll" and "\l/". You'll notice each spring pattern will require adjusting of the spring claw screws (of course). It'll also effect the movement and "bounce" of the trem.
Play around and experiment, changing springs is easy as pie.
Yeah, someone posted one of Huf's guitars in the "Horrible Guitarland" thread (funny enough, it was started by Huf ) and then some guy, Guinness, supposedly from Liverpool said he bought the guitar and that it was amazing, etc. Well, according to S7eve he had a Swiss Com IP, thus couldn't be from Liverpool. He also questioned the fellows odd accent which was very similar to Huf.
Was it Huf? We'll never know. He's not the only fella in all of Switzerland.
I thought about things to do, some real thorn in the side shit. Between work, personal, etc. I have several e-mails, I could easily make a few accounts over on "Metal Guitars", and just post all kinds of hilarity, but it would be childish.
Besides, I'm kinda over the initial "WTF", so I think I'm going to be the bigger man and watch them go down in blazing "glory" all on their own.
