[flame] I find it ridiculous to extend a steerer to lofty altitudes, only to bring the bars down with a negative rise stem.
Can't stomach a positive rise?
At the very least, try to find a zero-rise stem to reduce the spacer stack, along with stress and flex of the steerer.

Aesthetics aren't everything, you know.[/flame]

Edit: What applies for one type of steerer doesn't necessarily hold for the next.
ie. Many 1" threadless steerers are Al, and have real issues with flex.
Steel is a far superior choice IMO, for that diameter Ahead system. Some manufacturers have seen the light.
