Handlebar rise height?

I have a 2008 enduro pro. I just replaced the stock 660mm mid rise bars with some 661 vone 711mm low rise (19mm) bars. I know there's a getting used to stage but something felt really off when I gave it a try yesterday. the bike just felt really unstable on super rocky technical stuff. I thought things were going to feel more stable on that stuff with the wider bars. I just wanted to get some opinions. Low or mid rise? wider or narrower? What is it going to do the geometry of the bike? Where will I feel the differences?
