Replying to S2 Jago Mounting Position?

What up NS

I just got my S2 Jagos for this season, and had them mounted at the +6 mark. (What Rossi Recomends for park) Well when I brought them into the shop, (The same shop that mounted them) they proceed to tell me that i have 2 more inches of tail then tip. WHAT THE FUCK. I emailed Rossignol directly on Feb 20, still no response. I dont know why Rossignol would ever recommend skis to be forward mounted. I thought I could trust them with a mounting position, but I guess not. So hey Rossignol, FUCK YOU. /Rant
