I was playing around with my 2.0 compact trying the different back straps on the gun. I've been using the small since I got the gun because I felt it would conceal better, but switched to the ML. The ML feels better in my hand and points better. It also seems to cause me to get a more consistent placement of my finger on the trigger resulting in slightly better groupings. I'm just curious to see which one others have found to work best for them.
