I'd get either a Thomson X2 or an EA90 myself, just depending on how spontaneous I feel.

I have the EA90. Its Easton's newest aluminum stem. Its light and stiff enough. I had an Oval Concepts stem and that was the stiffest I've used, but weighs about what a Thompson X2 weighs, which is not on the light end of the scale. In addition the collar is much taller than other stems, so it changes up the stack height and spacers considerably.
The Thompson X2 is a nice, stiff stem, beautifully machined, and a reasonable weight: on the heavier end of whats considered light. I would reject the X4 and exchange it for one of the following:
Thompson X2
Ritchey WCS
Easton EA90
