I have recently purchased the Rossignol SC80 flat, ski length 185cm and mounted it with the Rossignol Axial2 120 binding at the recommended mounting point, against my suggestion to the shop.
My problem is that I cannot ski balanced in every situation on this ski but can when skiing many others that I have demoed. With this ski I find myself in the back seat and working hard to keep forward. I am especially off balance in the back seat on steep runs with bumps that are packed powder or ice, especially if the bumps are deep. Skiing any pitch in fresh powder or doing GS turns on any pitch of groomed or ICE is not a problem.
I ski in advanced conditions, steep tree and mogul runs that are powder or crud 70% of the time but ICE or packed powder 30% of the time. I ski at an advanced level having very good awareness of my balance 90% of the time. I am a 6 foot, 190 pounds and a strong skier. I use a size 28.5 Dalbello Krypton Pro ID boot with both forward lean adapters added.
So my questions are as follows: Is the ski mounted too far forward, the mounting line is 87 cm from the tail and I find at this point the ski has too much tail? Is the ski too long for what I am trying to do? Is this the wrong ski altogether? Is the boot forward lean, ramp angle etc too much for my ankle flexion causing me to lean back to compensate? Or finally is the binding ramp angle too much, I believe it is 1.5 degrees?
I am just starting to get into the technical aspects of ski and boot setup and find this quite interesting and would like to hear what others have to say.
