Just a few phots to help you out. I seriously believe if you are really a strong skier you can't go wrong with the 179 bent. When you have longer skis you can get better much faster.
The 179 bent will measure about the same as a 184 bibby which i have.
When they are side by side you maybe have 6 cm more at the tip and 4 at the tail. They only look big when they're not on your feet.
