I had some Ergon type grips, and really didn't like them. Too big and chunky, and I have big hands. So you're not alone there.

If you want to try a narrower bar, it's very easy: just loosen your components and slide them inboard. You can leave the handlebar end sticking out the end of the grip for a while to see if you like a narrower position. If that doesn't work, you can try butterfly bars, swept back bars, etc.
