I recommend using the suggested mount point on the ski. I've used them at true center, -2 and recommended. Not the ski for true center (in my opinion) and -2 feels like a different ski would feel at true center.
If you're unsure and have to ask it's always a great call to go with the recommended line that is put on the ski. Despite what some people might think, this line is carefully placed in this location after rounds of testing and tons of feedback from engineers, athletes and other people who helped develop the ski.
Best of luck and hope you like the Poachers!
