Ultegra 6600 triple shifter with a double crank

Can a Shimano Ultegra 6600 left hand "triple" shifter be set up to function decently on a double crank? If so, any helpful hints as to how to set the limit stops and what it will feel like, will it have an additional click or two with the small lever that won't accomplish anything? (I think there used to be a trim position on this series, wasn't there?)
As always, thank you for input.

I don't know the specifics of the Ultegra shifter, I've done this on other Shimano 3x shifters. I always have the inside chainring index as the unused shifter index and use the two outer index positions for the two chainrings. I set the adjustment screws for the two chainrings, if I shift into to un-used index, the cable gets slack and the adjustment screw stops the derailleur movement.

Yup, it will work.
I received my bike as a handed down gift, and it came with the exact setup you are describing.

I did the same thing.
Sometimes have to click twice to shift (usually after I've bumped it on something, or the kids' accidentally hit it while putting their bike away). Even then it works fine with no problems. You only need to ensure you limit the derailleur so it doesn't push your chain off.

At first it bothered me that it wasn't perfect, 2 rings - 2 clicks, but really, it's not that big of a deal. Especially when I weighed the situation with how much it would cost for new shifters, and installation.

6600 is 9-speed right?

If so, the shifter's the same whether for a double or triple crankset. The shifter should have 4 positions. As a double you get 2 shift positions for each chainring. As a triple you get one position for the granny. 2 for the middle ring and one for the big ring. I'm sure that's the way that Shimano intended because I used to have a double chainring road bike and a triple chainring tandem. I had Flight Deck computers on both bikes and both Flight Decks always indicated the appropriate chainring that I was in.

6600 is first generation 10 speed and double/triple specific but he can still use a triple on a double as noted above.
