I made a switch to Radar Pulse boots last year from Vectors and was always bothered by the front boot, and how it looked like it was slightly biased to the big toe side. There were no alignment marks, so the binding was just mounted in the center of the adjustment slots.
I ran my PB with that setup on a Senate at the time, then after a series of events (broke ski, crashed, torn bicep tendon)switched to a Vapor and struggled with it. This spring, I rotated the front binding in the adjustment slots to be more "straight" at the toes. I'm LFF, so it was just a very slight twist to the left. Looking at the ski, the toes are visually "straight" looking on the ski now. Now I'm also a bit duck footed.
The ski was instantly better, and while our course isn't in yet, I'm free skiing worlds better then last year, with more control and better confidence.
Perhaps I misunderstood front binding alignment, but now with that ever so slight rotation, its much better.
