I feel like the Alpinas have largely gone out of style though. While they are still super stiff, they are very deep. Many (most?) high-end carbon frames have gone with incredibly short head tubes, meaning one has to run a lot of spacers and an upturned stem to get the hand position right on those Alpinas, compared with a shorter drop bar like Look or Scatto.
Older frames and many of the aluminum offerings still have fairly tall head tubes, so the Alpinas work better there.
Also, I found the 33s to be way too narrow for my liking.
