Another handlebar option, if you're interested in working with one of your current bikes or retrofitting another one, is a so-called butterfly bar (I've also seen it called a trekking bar). Here's my 1997 Trek 750 with one:

I took it off and put a MTB riser bar on it, but I'm going to try the butterfly bar again on it. There are a lot of hand position options, and you can get a butterfly bar in different sizes and shapes/contours. Some are a little more "squatty" front to rear, some are more rounded, almost circular-shaped. Mine are 570mm wide, which is about at the narrow range for me (I prefer at least that wide). But I have wide MTB bars (with bar ends) on my Roam and wide MTB bars (without bar ends) on my MTB, and I'd like something different on this 750, so I'm trying the butterfly again, but with thumb shifters this time (for more grip area on the straight sections).
