Binding placement

I have the 12' Ronix parks setup. I usually ride with the boots all the way out and about 15 degrees. However, I coming off a femur injury and lately, I feel like it puts strain on my legs. I also feel like my pop sucks now.

Basically what Im asking is, beside comfort, what does you width of your stance change as far as board control and landings etc.

I know its a dumb question but I always get too excited to change my board setup when Im out there. I usually just leave it as it is.
