Aero Bars on road bike?

Been there, done that. Had a klein and added aerobars. Rode it about 5 times and wasn't comfortable for more than about an hour. Ended up buying a tri-bike, took the bars off the road bike, gave 'em away. And you're right...I wasn't in a good position, didn't have the fit, and didn't enjoy the whole experience.  

In your shoes, I wouldn't put full aerobars on a road bike.  On a very hilly course, especially if you're just getting your bike groove, the difference between aerobars and drops is not as pronounced as a flat, draft legal race (IMFL). Just kidding, IMFL peeps.  You prolly wouldn't notice it.  

One thing to consider might be the shorty aerobars. Used in ITU races, the pros add them to their road bike setup to get more aero. You get the penalty of your drops out in the wind, but you get the much bigger benefit of your body being narrow...and the additional handling that comes with being on a road bike. 

Shorty aeros?  Wha...?  Pics? links?  PGCG won't let me cough up the cash for a tri bike so I was going to add aeros to my road bike.  I'd like to hear more...

Yeh, that's them. The big benefit is that they narrow you. You're the biggest aerodrag on the bike (no offense, e, I am too), and part of that drag is the wind that your front catches. So instead of having your arms 2 ft apart like you're welcoming the wind, have 'em 8 inches apart, like you're staying out of the wind.

In other words, anything you can do to narrow your profile is great. They're proven, they work. ITU races them exclusively.

I have aero bars on my hybrid.  Most said the same thing about the fit, weight, etc.  I found a set on clearance for $20 and decided to try them.  My primary reason for wanting them was actually more for comfort than speed or aero.  My hands go numb fairly quikly due to some long time nerve issues. 

The aero bars have eliminated the numbness as I have more alternatives for position.  Also, whenever I go into aero, I gain .5 -.75 mph almost instantly. 

I am finding that I spend more and more time in aero.

I use the Profile Design T2+ aerobars on my Scott road bike and I wouldn't be w/out them. There was definitely a little "tweaking" that needed to be done to my fit, but once I got it dialed in they are extremely comfortable.

One of the biggest changes you would want to make if you put aerobars on your road bike is the seat. Not only the geometry, but buy yourself a tri-specific saddle, you won't be sorry.
