I like wide bars myself--more stable, less twitchiness on rough trails. I have a 685mm/27 inch bar on my Santa Cruz and that felt wide/weird at first as I came off a 90s hardtail after 20 years but I got used to it after a couple weeks and wouldn't go back to old school narrow. My new Kona has a 711mm/28 inch bar and I love that even more.
A few things that I found that effect bar-width feel is how much sweep is created or removed by how a riser bar is tilted in the stem. Tilted forward makes you reach and feel even wider on the grips. Folks should check that before making drastic cuts. Also, using a shorter stem will "narrow up" a wide bar as well as help a bike's descending and handling qualities. My Santa Cruz above came with a 90mm stem which paired well with the 685/27 bar. I spec'd an even shorter 70mm stem for the Kona with its 711/28 bar--it handles and feels awesome.
