I have a one piece aerobar on my multi sport bike. I posted this pic before, but will do so again to show you here:
Attachment 9570
I have since made some adjustments, such as swapping out that stem for an adjustable one to raise the height to meet my comfort level. I've been reading up about adding a brake such as this:

There are pros and cons, but I am considering it.
It is now possible for me to go on longer rides with pleasure. I look forward to it. Much, much less painful now. Not close to doing 100 mile stretches though! I don't do races or ride in large groups either. I ride just for the pure joy of it. I'm glad I have the aerobar now. I had to practice for a while to get used to the handling of the bike when in the aero position. I still get a panicky feeling when a big truck roars by and I feel caught up in the back draft. But, I don't like when that happens anyways. Most of my rides sound like yours Lakerider and the aerobar is working out very well indeed!
