There is another more recent thread on this same subject and I just did this myself. There is also a pic in that thread of my new bar setup.

After about 2 weeks of use, much happier with this bar setup. The old iso grips were probably just a tad more comfortable. But having a little wider bar and the bar ends far outweigh it.
