Replying to Scratch FS or Head Mojo 75 ?

I am looking at getting some head mojo 75 skis or a pair of scratch FS skis (the dark grey and yellow ones). I know that the head skis are like bomb proof, but how do the scratch skis compare to the head skis in the duribility part of things? If they were the same price i would def. go with the head skis but i can get the scratch skis brand new for $150 less than the head skis. Would the scratch skis hold up to 4 days of pure rails every week.
