I measured the insert pattern relative to the running length, and it appears that the middle inserts are set back about 5cm - can anyone confirm? That seems like a lot. My Donek was centered, my old FPs had 1.5 to 2.5cm of setback.
Saturday I got my first day on the board, and I started in the middle inserts. Each set of inserts is a basic "8-pack" which provides 3 possible positions. Using the same sets of inserts on each foot (forward/forward, middle/middle, rearward/rearward) results in a 19.25" stance width by my tape measure. How convenient, my usual width!
Not wanting a 5cm setback, I used the holes in the TD2s that shift the binding forward, so I think this resulted in about 3.5cm of setback. I felt like this was still a bit too far back, so I switched to the forward inserts on the board, and the holes in the bindings that shift the bindings back. I think this resulted in about 1.5cm of setback and that felt just right. Heelsides felt better after doing that.
Also I believe the "forward loaded camber" really likes to have your weight forward at the beginning of the carve.
