You mean the difference between "Full Race" and "Full Race Pro Team"? The difference is on the graphic.
But, when you will buy 2 different lengths, I prefer a "Race" (162) and one "Full Race" (185), the "Race" with the longer nose is much more easier to handle without different snow conditions, "Full Race" is a really hardcore racing maschine.
Maybe you will write me a U2U and we can talk in german.
