Because ulnar nerve damage (even post-surgery) limits how far I can ride without aerobars to about 20 minutes, at which point my left hand goes numb, I've used aerobars on all my bikes since the mid-1990s. I don't do rides of greater duration than about 5 hours, but I never yearn to ride without them.

My least favorite setup is drops plus aerobars. My favorite is bullhorns plus aerobars. The combination of flat bars plus aerobars is close to being as good as the bullhorn configuration, although getting the right configuration for comfort and efficiency was tricky.
