Replying to I'm losing sleep over this decision!

Ok, I'm buying arv's. I just don't know which ones. Tell me which deal you think I should take a or b. I'm 5'11' and 150lbs.
Both last years.

A) 185 ARV
New
Marker 1400ti bindings used for a season
Better skis worse bindings

B) 175 ARV
used 7 times
Rossi Power 100 used 7 times
Used but I like the bindings better
Less money

Help me out!
