Stihl lists the available guide bars for the 180 as 12" to 16". Has anybody used one with a 16" bar? I had a 180 with a 14" bar a few years ago and liked it. Didn't push it hard but it was a great little saw to have around. I was surprised that the catalog even listed a 16" bar as a possibility but it would often be easier on the back to have the longer bar.
