At first hello everybody!!!
I'm from Poland, country in Middle-East Europe. I ski on atomic sx11 from season 05/06. It's a very good ski and I donate it to everybody
I think the diffrences are as significant as you can feel them on snow. Sx10 is dedicate to more experienced skiers and have also b5 system, which made racing more comfortable. I think mates from community will say you more about divides between this two types of ski...
I have also a question. Could you tell me the prizes of new Atomic SX series in U.S.A. or Canada (I think about sx b5, sx 12bp, sx 10)??? I will be very glad to know
